How to Fix the ‘SyntaxError: missing ] after element list ‘ Error in Our JavaScript App?

Sometimes, we may run into the ‘SyntaxError: missing ] after element list’ when we’re developing JavaScript apps.

In this article, we’ll look at how to fix the ‘SyntaxError: missing ] after element list’ when we’re developing JavaScript apps.

Fix the ‘SyntaxError: missing ] after element list’ When Developing JavaScript Apps

To fix the ‘SyntaxError: missing ] after element list’ when we’re developing JavaScript apps, we should make sure we have corresponding closing bracket for any opening bracket in our JavaScript code.

We should also make sure we separate entries that are supposed to be separated by a comma with a comma.

For instance, the following code will all throw the error:

let list = [1, 2,

let instruments = [
  'Ukulele',
  'Guitar',
  'Piano'
};

let data = [{foo: 'bar'} {bar: 'foo'}];

The first line is missing the closing bracket.

The 2nd array has a closing brace instead of a closing bracket.

And the last array is missing a comma in between the 2 objects.

To fix them, we write:

let list = [1, 2];

let instruments = ["Ukulele", "Guitar", "Piano"];

let data = [{ foo: "bar" }, { bar: "foo" }];

Conclusion

To fix the ‘SyntaxError: missing ] after element list’ when we’re developing JavaScript apps, we should make sure we have corresponding closing bracket for any opening bracket in our JavaScript code.

We should also make sure we separate entries that are supposed to be separated by a comma with a comma.
