How would I remove blank characters from a string in JavaScript?
A trim is very easy, but I don't know how to remove them from inside the string. For example:
222 334 -> 222334

You can use a regex, like this to replace all whitespace:
var oldString = "222 334";
var newString = oldString.replace(/\s+/g,"");
Or for literally just spaces:
var newString = oldString.replace(/ /g,"");

This will work for most use cases, however not for unicode space characters.
You can also do this without a regular expression or a replace-
var string= string.split(' ').join('');

Nick Craver has a good response, if you're OK with regex, go for it.
I just want to add that you can do this without Regex as well. You can just use a normal JavaScript replace(), using the parameters (" ", "") to replace all whitespace with empty strings.
Update: Whoops, this won't work with multiple whitespaces.

This will also only replace the first occurrence of a space, not all of them.

Stefan: If tabs need to be pulled as well, then of course, Nick Craver's regex is best.

Thanks Cyrena, I have to add also that you are very beautiful
You can simply use trim().
See docs here.
