Remove all white space from string JavaScript

Question

How can I remove all the white space from a given string.

Say:

var str = "  abc de fog   ";
str.trim();

Gives abc de fog AND NOT abcdefog, which I want.

How can I get all the white space removed using JavaScript?

Could you rename the Subject to something else than "Trim"? It's misleading when you ask for "replacing" in the text of your question. — Melounek, May 13 '21 at 08:42

Use this:

str.replace(/\s+/g, '');

Instead of this:

str.trim()

Do you mind explaining the preference? I'm assuming it is due to the fact that `str` can be `null` or `undefined`? – Con Antonakos Jul 30 '18 at 17:49

```str.trim()``` only trims the trailing spaces at the beginning and end. The other solution strips out all the spaces from everywhere in the string. – Cute_Ninja Jul 30 '18 at 21:16
Ah, so silly of me! I misread OP's original intent. Thanks for clarifying! – Con Antonakos Jul 31 '18 at 04:17

This is not what OP wanted, he clearly said "abc de fog AND NOT abcdefog", `str.replace(/^\s+|\s+$/gm,'');` will do as @timothy-nwanwene suggested. – 0x48piraj Jul 16 '19 at 01:41
@0x48piraj you misread OP question. he wanted to strip ALL whitespace – Andre Figueiredo May 11 '21 at 15:38
