How to Fix "Uncaught SyntaxError: Unexpected identifier" in JavaScript

Since JavaScript is not a compiled language, you can get syntax errors when running your code.

One of these errors is the Uncaught SyntaxError: Unexpected identifier error.

In this post, we'll look at what causes this, examples of it, and how to fix it.

What causes this error?

This error is mainly caused by three things.

1. A missing bracket, quote, parenthesis, etc.
2. Extra brackets, quotes, parenthesis, etc.
3. A typo in a keyword like for, if, while, etc.

Examples of this error

Now that we know what causes it, let's look at a few examples of code that causes it.

Here's an example of declaring a const incorrectly:

JAVASCRIPT
Const array = [1, 2, 3, 4, 5];

BASH
SyntaxError: Unexpected identifier

Keywords in JavaScript are case-sensitive. That means that Const is not the same as const.

Now, let's look at an example of a missing comma, which will also trigger this error:

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

Because in this case, we are missing a comma after a: 1, this object was not able to be parsed correctly and therefore threw the error.

The fix is to ensure your code's syntax complies with the JavaScript syntax rules and you should be good to go.

Conclusion

In this post, we looked at what causes the Uncaught SyntaxError: Unexpected identifier error and how to fix it.

In most cases, it is just code that is not adhering to the JavaScript syntax rules or contains typos.

Hopefully, this post has helped you with your code!
