Javascript: String.replace for space isn't working

Question

I'm trying to get rid of spaces in a string, but it seems not to be working. This doesn't return the string without spaces:

"{ color: 'blue',".replace(" ",'') and "{ color: 'blue',".trim()

I've verified that those are spaces (char code 32), and I've even done this:

var x = "{ color: 'blue'," x.replace(x[1],'')

FYI, doing this in chrome's console. Am I going crazy?

I always find it weird that people mods mark questions as duplicate on SO even when the question/confusion is very different. Duplicate answers isn't the same thing as a duplicate question. — B T, Sep 14 '17 at 21:32
How is your confusion different than the one in https://stackoverflow.com/questions/6623231/remove-all-white-spaces-from-text ? — Felix Kling, Sep 14 '17 at 21:33
Because I didn't even realize it was removing *any* spaces. I just thought I was trapped in a waking nightmare — B T, Sep 14 '17 at 21:47
And you think this minor variance warrants a complete new question? Are the duplicates not useful to you? But ultimately it's not possible to satisfy everybody. I rather close more often than not often enough. Luckily I don't have the last word. If the community feels strongly about it they have ways to reopen the question. — Felix Kling, Sep 14 '17 at 21:49
This question is not what I feel strongly about. I'm just expressing that I wish SO had a way to distinguish "this question has answers that answer this question" from "duplicate question" markings. Its misleading in a lot of cases, and I know for a fact it causes a lot of strife in the community - especially with newbs. For what its worth, I think closing too often vs not often enough is kind of like innocent before proven guilty. Would you rather jail too many people than not enough? No. No you wouldn't. — B T, Sep 15 '17 at 21:38

It does remove space, but not all of them just the first one, to remove all you should do

let str = "{   color: 'blue',".replace(/ /g,'');

console.log(str);

ohhhhh, for crisake! Every time i run into this I curse the guy who decided replace should only do one at a time! – B T Sep 14 '17 at 21:24
But wait, why doesn't trim work tho? – B T Sep 14 '17 at 21:24
`/\s/g` can also use a regex and match the whitespaces, also gets tabs! – AHB Sep 14 '17 at 21:24
nm on trim - i'm dumb – B T Sep 14 '17 at 21:24
The trim() method removes whitespace from both ends of a string. You don't have that in your string – marvel308 Sep 14 '17 at 21:25
@BT But be careful as it removes spaces from the inner strings too: `{ a: 'b c' }` will become `{a:'bc'}` not `{a:'b c'}`. – ibrahim mahrir Sep 14 '17 at 21:27
this is not working for me – sergiol Jan 19 '23 at 11:55
I discovered why it is not working for me. I am getting a float number formatted via `Intl.NumberFormat` which puts a `&8239;` character narrow non-break space instead of a normal ASCII space as the thousands separator. – sergiol Jan 19 '23 at 12:02

Try something like this:

x= x.replace(/\s/g, '');
