# SyntaxError: Invalid destructuring assignment target in JS

The "SyntaxError: Invalid destructuring assignment target" error occurs when we make a syntax error when declaring or destructuring an object, often in the arguments list of a function.

To solve the error make sure to correct any syntax errors in your code.

Here are some examples of how the error occurs:

# Setting a variable to be equal to multiple objects

The first example throws the error because we set a variable to be equal to multiple objects without the objects being contained in an array.

Instead, you should place the objects in an array or only assign a single value to the variable.

declare array of objects or single object

The square brackets [] syntax is used to declare an array and the curly braces {} syntax is used to declare an object.

Arrays are a collection of elements and objects are a mapping of key-value pairs.

# Incorrectly destructuring in a function's arguments

The second example throws the error because we incorrectly destructure an object in a function's arguments.

If you're trying to provide a default value for a function, use the equal sign instead.

set default value for function parameter

And you can destructure a value from an object argument as follows.

destructuring value from object argument

Here's the same example but with arrays.

If you can't figure out where exactly the error occurs, look at the error message in your browser's console or your terminal (if using Node.js).

The screenshot above shows that the error occurs on line 11 in the index.js file.

JavaScript SyntaxError – Invalid destructuring assignment target

A JavaScript “SyntaxError: Invalid destructuring assignment target” error arises when the interpreter finds an invalid target on the left side of destructuring assignment, destructuring assignment makes it possible to unpack values from arrays or properties from objects into distinct variables but this can only be done with a correct syntax and target for such assignments.

Understanding an error

In JavaScript , an "Invalid destructuring assignment target" error means that either the syntax for the destructuring assignment is wrong or the pattern (array/object destructuring) does not match to assign targets when JavaScript has data being destructured it expects valid patterns that are similar to their structure, let’s look at this error, what causes it and how it can be resolved by giving examples.

Case 1: Error Cause: Incorrect Array Destructuring

Example: Making use of wrong syntaxes or invalid patterns in array destructuring assignment bring about such an error.

Resolution of error

On the right hand side of array destructuring assignment there should be an iterable source such as an array or any other iterable objects.

Case 2: Error Cause: Incorrect Object Destructuring

Example: If you use incorrect patterns or try to destructure non-object values in an object destructuring assignment this error will be thrown.

Object destructuring assignment requires an object on the right-hand side with properties matching the destructuring pattern.

Case 3: Error Cause: Invalid Pattern Matching

Example: You will get this error when you try destructuring an object without stating property names that exist or using mismatch patterns to do so.

Make it a point to have the names for properties there in a destructuring pattern correspond with those in an object where it is pulled apart.

To avoid “Invalid destructuring assignment target” errors in JavaScript, ensure that the structure of arrays or objects being destructured matches with both the assignment targets and de-structuring patterns, proper unpacking of values into distinct variables depends on conforming to JavaScript’s rules of syntax for destructing assignments leading to those “Invalid destructuring assignment target”.

Destructuring assignment

The destructuring assignment syntax is a JavaScript expression that makes it possible to unpack values from arrays, or properties from objects, into distinct variables.

Description

The object and array literal expressions provide an easy way to create ad hoc packages of data.

The destructuring assignment uses similar syntax but uses it on the left-hand side of the assignment instead. It defines which values to unpack from the sourced variable.

Similarly, you can destructure objects on the left-hand side of the assignment.

This capability is similar to features present in languages such as Perl and Python.

For features specific to array or object destructuring, refer to the individual examples below.

Binding and assignment

For both object and array destructuring, there are two kinds of destructuring patterns: binding pattern and assignment pattern , with slightly different syntaxes.

In binding patterns, the pattern starts with a declaration keyword ( var , let , or const ). Then, each individual property must either be bound to a variable or further destructured.

All variables share the same declaration, so if you want some variables to be re-assignable but others to be read-only, you may have to destructure twice — once with let , once with const .

In many other syntaxes where the language binds a variable for you, you can use a binding destructuring pattern. These include:

The looping variable of for...in for...of , and for await...of loops;
Function parameters;
The catch binding variable.

In assignment patterns, the pattern does not start with a keyword. Each destructured property is assigned to a target of assignment — which may either be declared beforehand with var or let , or is a property of another object — in general, anything that can appear on the left-hand side of an assignment expression.

Note: The parentheses ( ... ) around the assignment statement are required when using object literal destructuring assignment without a declaration.

{ a, b } = { a: 1, b: 2 } is not valid stand-alone syntax, as the { a, b } on the left-hand side is considered a block and not an object literal according to the rules of expression statements . However, ({ a, b } = { a: 1, b: 2 }) is valid, as is const { a, b } = { a: 1, b: 2 } .

If your coding style does not include trailing semicolons, the ( ... ) expression needs to be preceded by a semicolon, or it may be used to execute a function on the previous line.

Note that the equivalent binding pattern of the code above is not valid syntax:

You can only use assignment patterns as the left-hand side of the assignment operator. You cannot use them with compound assignment operators such as += or *= .

Default value

Each destructured property can have a default value . The default value is used when the property is not present, or has value undefined . It is not used if the property has value null .

The default value can be any expression. It will only be evaluated when necessary.

Rest property

You can end a destructuring pattern with a rest property ...rest . This pattern will store all remaining properties of the object or array into a new object or array.

The rest property must be the last in the pattern, and must not have a trailing comma.

Array destructuring

Basic variable assignment, destructuring with more elements than the source.

In an array destructuring from an array of length N specified on the right-hand side of the assignment, if the number of variables specified on the left-hand side of the assignment is greater than N , only the first N variables are assigned values. The values of the remaining variables will be undefined.

Swapping variables

Two variables values can be swapped in one destructuring expression.

Without destructuring assignment, swapping two values requires a temporary variable (or, in some low-level languages, the XOR-swap trick ).

Parsing an array returned from a function

It's always been possible to return an array from a function. Destructuring can make working with an array return value more concise.

In this example, f() returns the values [1, 2] as its output, which can be parsed in a single line with destructuring.

Ignoring some returned values

You can ignore return values that you're not interested in:

You can also ignore all returned values:

Using a binding pattern as the rest property

The rest property of array destructuring assignment can be another array or object binding pattern. The inner destructuring destructures from the array created after collecting the rest elements, so you cannot access any properties present on the original iterable in this way.

These binding patterns can even be nested, as long as each rest property is the last in the list.

On the other hand, object destructuring can only have an identifier as the rest property.

Unpacking values from a regular expression match

When the regular expression exec() method finds a match, it returns an array containing first the entire matched portion of the string and then the portions of the string that matched each parenthesized group in the regular expression. Destructuring assignment allows you to unpack the parts out of this array easily, ignoring the full match if it is not needed.

Using array destructuring on any iterable

Array destructuring calls the iterable protocol of the right-hand side. Therefore, any iterable, not necessarily arrays, can be destructured.

Non-iterables cannot be destructured as arrays.

Iterables are only iterated until all bindings are assigned.

The rest binding is eagerly evaluated and creates a new array, instead of using the old iterable.

Object destructuring

Basic assignment, assigning to new variable names.

A property can be unpacked from an object and assigned to a variable with a different name than the object property.

Here, for example, const { p: foo } = o takes from the object o the property named p and assigns it to a local variable named foo .

Assigning to new variable names and providing default values

A property can be both

Unpacked from an object and assigned to a variable with a different name.
Assigned a default value in case the unpacked value is undefined .

Unpacking properties from objects passed as a function parameter

Objects passed into function parameters can also be unpacked into variables, which may then be accessed within the function body. As for object assignment, the destructuring syntax allows for the new variable to have the same name or a different name than the original property, and to assign default values for the case when the original object does not define the property.

Consider this object, which contains information about a user.

Here we show how to unpack a property of the passed object into a variable with the same name. The parameter value { id } indicates that the id property of the object passed to the function should be unpacked into a variable with the same name, which can then be used within the function.

You can define the name of the unpacked variable. Here we unpack the property named displayName , and rename it to dname for use within the function body.

Nested objects can also be unpacked. The example below shows the property fullname.firstName being unpacked into a variable called name .

Setting a function parameter's default value

Default values can be specified using = , and will be used as variable values if a specified property does not exist in the passed object.

Below we show a function where the default size is 'big' , default co-ordinates are x: 0, y: 0 and default radius is 25.

In the function signature for drawChart above, the destructured left-hand side has a default value of an empty object = {} .

You could have also written the function without that default. However, if you leave out that default value, the function will look for at least one argument to be supplied when invoked, whereas in its current form, you can call drawChart() without supplying any parameters. Otherwise, you need to at least supply an empty object literal.

For more information, see Default parameters > Destructured parameter with default value assignment .

Nested object and array destructuring

For of iteration and destructuring, computed object property names and destructuring.

Computed property names, like on object literals , can be used with destructuring.

Invalid JavaScript identifier as a property name

Destructuring can be used with property names that are not valid JavaScript identifiers by providing an alternative identifier that is valid.

Destructuring primitive values

Object destructuring is almost equivalent to property accessing . This means if you try to destruct a primitive value, the value will get wrapped into the corresponding wrapper object and the property is accessed on the wrapper object.

Same as accessing properties, destructuring null or undefined throws a TypeError .

This happens even when the pattern is empty.

Combined array and object destructuring

Array and object destructuring can be combined. Say you want the third element in the array props below, and then you want the name property in the object, you can do the following:

The prototype chain is looked up when the object is deconstructed

When deconstructing an object, if a property is not accessed in itself, it will continue to look up along the prototype chain.

Fix Invalid destructuring assignment target in JavaScript

Learn, how to fix the “SyntaxError: Invalid destructuring assignment target” in JavaScript.

The “Invalid destructuring assignment target” error occurs, when we write a wrong syntax while destructuring an object or defining a new object, often in the arguments list of a function.

Here are example, of how the following error occurs:

In the example above, the error occurs because we initialized the multiple objects to a same variable.

To fix this error, makesure check the syntax while writing the code.

Now, we’ve fixed the error by placing the two objects in a array and assign it to the variable.

Here in an another example, how the error occurs:

In the example above, the error occurs because we are destructuring the object using the syntax ['name', 'place'] which wrong syntax, to fix the error we should destructure the object in Correct way Eg: {name, place}.

Invalid Destructuring Assignment Target: What It Is and How to Fix It

Invalid Destructuring Assignment Target

Destructuring assignment is a powerful JavaScript feature that allows you to extract multiple values from an object or array into separate variables. However, it can be easy to make mistakes when using destructuring assignment, and one common error is to use an invalid target.

In this article, we’ll discuss what an invalid destructuring assignment target is, how to identify it, and how to fix it. We’ll also provide some examples of invalid destructuring assignment targets so that you can avoid making this mistake in your own code.

What is an Invalid Destructuring Assignment Target?

An invalid destructuring assignment target is a variable that is not a valid reference to a JavaScript object or array. This can happen if the variable is , null, a function, or a primitive value.

For example, the following code is invalid because the variable `x` is :

const { x } = obj;

The variable `x` is , so it cannot be used as a target for destructuring assignment.

How to Identify an Invalid Destructuring Assignment Target

There are a few ways to identify an invalid destructuring assignment target.

The variable is or null. If the variable does not exist, it cannot be used as a target for destructuring assignment.
The variable is a function. Functions cannot be used as targets for destructuring assignment.
The variable is a primitive value. Primitive values, such as numbers, strings, and booleans, cannot be used as targets for destructuring assignment.

How to Fix an Invalid Destructuring Assignment Target

To fix an invalid destructuring assignment target, you need to make sure that the variable is a valid reference to a JavaScript object or array.

If the variable is or null, you can assign it a value before using it for destructuring assignment.
If the variable is a function, you can use the `call()` or `apply()` method to call the function with the destructuring assignment targets as arguments.
If the variable is a primitive value, you can wrap it in an object or array before using it for destructuring assignment.

Examples of Invalid Destructuring Assignment Targets

The following are examples of invalid destructuring assignment targets:

`function()`
`”string”`
`[1, 2, 3]`

Destructuring assignment is a powerful JavaScript feature, but it’s important to be aware of the invalid destructuring assignment targets. By following the tips in this article, you can avoid making this mistake in your own code.

Destructuring assignment is a JavaScript feature that allows you to extract the values of multiple properties from an object or array into separate variables. For example, the following code uses destructuring assignment to extract the `name` and `age` properties from the `user` object into separate variables:

const { name, age } = user;

This code is equivalent to the following code, which uses the `Object.keys()` and `Object.values()` methods to iterate over the `user` object and extract the values of the `name` and `age` properties:

const name = user.name; const age = user.age;

Destructuring assignment can be a very convenient way to access the values of multiple properties from an object or array. However, it is important to be aware of the potential for invalid destructuring assignment targets.

What is an invalid destructuring assignment target?

An invalid destructuring assignment target is a JavaScript expression that cannot be used as the target of a destructuring assignment. This can occur for a variety of reasons, such as:

The expression is not a valid JavaScript object.
The expression is a reference to a property that does not exist.
The expression is a reference to a property that is not an object.

How to identify an invalid destructuring assignment target?

There are a few ways to identify an invalid destructuring assignment target:

The JavaScript compiler will typically generate an error when you attempt to perform a destructuring assignment to an invalid target.
You can also use the `typeof` operator to check the type of an expression. If the expression is not a valid JavaScript object, it will not be a valid destructuring assignment target.
You can also use the `Object.prototype.hasOwnProperty()` method to check if an expression refers to a property that exists. If the property does not exist, it will not be a valid destructuring assignment target.

Examples of invalid destructuring assignment targets

“: The “ value is not a valid JavaScript object, so it cannot be used as the target of a destructuring assignment.
`null`: The `null` value is not a valid JavaScript object, so it cannot be used as the target of a destructuring assignment.
`0`: The number `0` is not a valid JavaScript object, so it cannot be used as the target of a destructuring assignment.
`”string”`: The string `”string”` is not a valid JavaScript object, so it cannot be used as the target of a destructuring assignment.
`function()`: The function `function()` is not a valid JavaScript object, so it cannot be used as the target of a destructuring assignment.
`[]`: The array `[]` is not a valid JavaScript object, so it cannot be used as the target of a destructuring assignment.

Invalid destructuring assignment targets can cause errors in your JavaScript code. It is important to be aware of the potential for invalid destructuring assignment targets and to take steps to avoid them.

Here are a few tips for avoiding invalid destructuring assignment targets:

Use the `typeof` operator to check the type of an expression before using it as the target of a destructuring assignment.
Use the `Object.prototype.hasOwnProperty()` method to check if an expression refers to a property that exists.
Use the `Object.keys()` method to get a list of the properties of an object.
Use the `Object.values()` method to get a list of the values of an object.

By following these tips, you can help to ensure that your JavaScript code is free of invalid destructuring assignment targets.

3. How to fix an invalid destructuring assignment target?

To fix an invalid destructuring assignment target, you need to make sure that the expression is a valid JavaScript object. This means that the expression must:

Be a reference to an existing object.
Be a reference to a property that exists on the object.
Be a reference to a property that is an object.

If the expression does not meet these criteria, you will get an error when you try to destructure it.

Here are some examples of how to fix invalid destructuring assignment targets:

`’foo’` is not a valid JavaScript object, so you cannot destructure it. To fix this, you can either assign it to a variable first, or you can use the `Object.assign()` method to create a new object with the value of `’foo’`.
`123` is not a valid JavaScript object, so you cannot destructure it. To fix this, you can either assign it to a variable first, or you can use the `Number.prototype.toObject()` method to convert it to a JavaScript object.
`[1, 2, 3]` is not a valid JavaScript object, so you cannot destructure it. To fix this, you can either assign it to a variable first, or you can use the `Array.prototype.toObject()` method to convert it to a JavaScript object.
`{ foo: ‘bar’ }` is a valid JavaScript object, so you can destructure it.
`obj.foo` is a valid JavaScript object, so you can destructure it.
`obj.bar` is not a valid JavaScript object, so you cannot destructure it. To fix this, you can either assign it to a variable first, or you can use the `Object.assign()` method to create a new object with the value of `obj.bar`.
`obj.baz` is not a valid JavaScript object, so you cannot destructure it. To fix this, you can either assign it to a variable first, or you can use the `Object.assign()` method to create a new object with the value of `obj.baz`.

Once you have fixed the invalid destructuring assignment target, you should be able to destructure it without any errors.

4. Examples of invalid destructuring assignment targets

`’foo’`
`{ foo: ‘bar’ }`
`obj.foo` (where `obj` does not exist)
`obj.bar` (where `obj.bar` does not exist)
`obj.baz` (where `obj.baz` is not an object)

These examples are all invalid because they do not meet the criteria for a valid JavaScript object.

`’foo’` is not a JavaScript object, so it cannot be destructured.
`123` is not a JavaScript object, so it cannot be destructured.
`[1, 2, 3]` is not a JavaScript object, so it cannot be destructured.
`{ foo: ‘bar’ }` is a JavaScript object, so it can be destructured.
`obj.foo` is a JavaScript object, so it can be destructured.
`obj.bar` is not a JavaScript object, so it cannot be destructured.
`obj.baz` is not a JavaScript object, so it cannot be destructured.

If you try to destructure any of these expressions, you will get an error.

Invalid destructuring assignment targets can be a pain to deal with, but they can be fixed by making sure that the expression is a valid JavaScript object. If you are having trouble fixing an invalid destructuring assignment target, you can always ask for help from a JavaScript expert.

Q: What is an invalid destructuring assignment target?

A: An invalid destructuring assignment target is a JavaScript expression that cannot be used as the target of a destructuring assignment. This can happen for a variety of reasons, such as if the expression is not a valid object or array, or if it contains duplicate property names.

Q: What are some common causes of invalid destructuring assignment targets?

A: Some common causes of invalid destructuring assignment targets include:

Using a non-object or non-array expression as the target of a destructuring assignment. For example, you cannot use a string or number as the target of a destructuring assignment.
Using an object or array that contains duplicate property names. For example, the following code will generate an error:

const { a, a } = { a: 1, b: 2 };

Using an object or array that contains a property that is not a valid JavaScript identifier. For example, the following code will generate an error:

const { foo[0] } = { foo: [1, 2, 3] };

Q: How can I fix an invalid destructuring assignment target?

A: To fix an invalid destructuring assignment target, you need to either make the expression valid, or remove the destructuring assignment.

To make the expression valid, you can:
Use an object or array that does not contain duplicate property names.
Use an object or array that does not contain properties that are not valid JavaScript identifiers.
To remove the destructuring assignment, you can simply remove the assignment operator (`=`) from the code.

Q: What are the consequences of using an invalid destructuring assignment target?

A: Using an invalid destructuring assignment target can result in a JavaScript error. This error can prevent your code from running correctly.

Q: How can I prevent invalid destructuring assignment targets in my code?

Use a linter to check your code for errors.
Use a static type checker to check your code for errors.
Manually review your code to ensure that all destructuring assignment targets are valid.

Q: Are there any other resources that I can use to learn more about invalid destructuring assignment targets?

A: Yes, there are a number of resources that you can use to learn more about invalid destructuring assignment targets. Here are a few of them:

[MDN Web Docs: Destructuring Assignment](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Destructuring_assignment)
[Stack Overflow: Invalid destructuring assignment target](https://stackoverflow.com/questions/3242563/invalid-destructuring-assignment-target)

Here are the key takeaways from this article:

An invalid destructuring assignment target occurs when you try to assign a value to a variable that is not a valid target for destructuring.
The most common cause of this error is trying to destructure a value that is not an array or object.
You can fix this error by making sure that the value you are trying to destructure is a valid target for destructuring.
You can also use the `.entries()` method to convert an iterable object into an array, which will make it a valid target for destructuring.

By following these tips, you can avoid invalid destructuring assignment targets in your own code.

SyntaxError: Invalid destructuring assignment target

I am following the “MERN Stack Course - ALSO: Convert Backend to Serverless with MongoDB Realm” video on Youtube from freeCodeCamp.org and can’t get past an error I’m getting. I am using the same code as the video but have a companies database instead of restaurants and different fields. Not sure if maybe there is an issue due to that, but I’m getting an error of :

The code for the file companiesDAO.js is:

I can include code for the other files if needed. Any ideas?

From just this information, it looks like the problem is that at some point in the code there is a destructuring assignment referencing filters . The value null cannot be destructured.

Thanks! The only other page with “filters” code is the controller file:

Nothing I’ve tried has worked so far. If there’s nothing further to try I’ll set up another database with the exact code from the video and mongodb database setup and see if I can get that working and go from there.

What happens if instead of initializing filters to null , you use and empty object?

I tried that and I get the same error but for the next item:

If I initialize everything to an empty object, I can start the server, but when I go to http://localhost:5000/api/v1/companies , I get a “this site cannot be reached, localhost refused to connect” page and the error in the console is:

Looks like there is an issue with my setup , I created a new project and followed the video exactly and got to where I was before and was able to get the data from the database.

I did start the initial project on a Next.js app I am building so there’s probably an issue there. Any info on possible conflicts in creating a backend like in the “MERN Stack Course - ALSO: Convert Backend to Serverless with MongoDB Realm” but on Next.js would be greatly appreciated!

Sorry I wasn’t more help. This sort of problem can be really tricky to track down.

No worries, I should have looked for a Next.js specific resource. Thankfully I was able to find a " How to Integrate MongoDB Into Your Next.js App" how-to directly from Mongodb, I’m hoping that’ll do the trick!

Good luck and happy coding!

The destructuring assignment syntax unpack object properties into variables:

It can also unpack arrays and any other iterables:

Object Destructuring

The order of the properties does not matter:

Destructuring is not destructive.

Destructuring does not change the original object.

Object Default Values

For potentially missing properties we can set default values:

String destructuring.

One use for destructuring is unpacking string characters.

Destructuring can be used with any iterables.

Array Destructuring

We can pick up array variables into our own variables:

Skipping Array Values

We can skip array values using two or more commas:

Array Position Values

We can pick up values from specific index locations of an array:

The Rest Property

You can end a destructuring syntax with a rest property.

This syntax will store all remaining values into a new array:
