Remove Trailing Spaces from a String in JavaScript

Remove Trailing Spaces from a String #

Use the trimEnd() method to remove the trailing spaces from a string. The trimEnd method returns a new string representing the original string stripped of any trailing spaces.

index.js

Copied!
const str = '  apple      ';

// 👇️ remove trailing spaces
const withoutTrailingSpaces = str.trimEnd();
console.log(withoutTrailingSpaces); // 👉️ "  apple"

// 👇️ remove both leading and trailing spaces
const withoutLeadingAndTrailing = str.trim();
console.log(withoutLeadingAndTrailing); // 👉️ "apple"

We used the String.trimEnd method to remove the trailing spaces from a string.

The trimEnd method does not change the original string, instead it returns a new string stripped of any trailing whitespace. Strings are immutable in JavaScript.

If the string contains no trailing spaces, the trimEnd method returns a copy of the original string, without throwing any errors.

index.js

Copied!
const str = 'test'.trimEnd();
console.log(str); // 👉️ "test"

When the trimEnd method is used on a string that contains trailing spaces, the new string has an updated length.

index.js

Copied!
const str = 'test    ';
console.log(str.length); // 👉️ 8

const trimmed = str.trimEnd();
console.log(trimmed.length); // 👉️ 4

If you want to remove the leading and trailing space from a string, use the trim method instead.
