Remove spaces from string JavaScript

  • by

You can use the replace() method with the regex in JavaScript to remove spaces from the string. Or use The trim() method to remove whitespace from both sides of a string.

.replace(/ /g,'')

The g character makes it a “global” match, repeating the search through the entire string.

If you want to match all whitespace, and not just the literal space character, use \s instead:


Remove spaces from string JavaScript

Simple example code

<!DOCTYPE html>

    const stripped = '    My String With A    Lot Whitespace  ';
    var res = stripped.replace(/\s+/g, '')



Remove spaces from string JavaScript

You can also remove all whitespaces from a text by using String.prototype.split and String.prototype.join:

const text = ' a b    c d e   f g   ';
const newText = text.split(/\s/).join('');

console.log(newText); // prints abcdefg

Using split and join methods

Alternatively, you can use the split method to split the string by spaces and then use the join method to concatenate the array back into a string without spaces:

let str = "Hello World! How are you?";
let result = str.split(' ').join('');
console.log(result); // "HelloWorld!Howareyou?"
