Remove the leading Spaces from a String in JavaScript

Remove the leading Spaces from a String #

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

Copied!
const str = '       hello  ';

// 👇️ remove leading spaces
const withoutLeadingSpaces = str.trimStart();
console.log(withoutLeadingSpaces); // 👉️ "hello  "

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

We used the String.trimStart method to remove the leading spaces from a string.

If the string contains no leading spaces, a copy of it gets returned from trimStart and no error is thrown.

Copied!
const str = 'example'.trimStart();
console.log(str); // 👉️ "example"

When the trimStart method is used on a string that contains leading spaces, the new string has a new length.

Copied!
const str = '   example';
console.log(str.length); // 👉️ 10

const withoutLeadingSpaces = str.trimStart();
console.log(withoutLeadingSpaces.length); // 👉️ 7

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