How to remove white space from a string?

Good evening, I am trying to find a way to remove white space from a string in JS, but as of right now, I have found no solution.

Here is some example code:

var Array = [];

var foo = "Hello";

var voo = "World";

if (foo != null){

  Array.push(foo);

}

if (voo !- null){

  Array.push(voo):

}

console.println(Array.join(', ');

\\Results: "Hello , World"\\

\\The space left of the comma should not be there\\

That really is the short of it.

Is there any way to remove spaces from a string, or at least from an Array?

That, or remove the space from the left of the comma?

Thank you!

Your code contains multiple errors (at least four), but after fixing it I'm not getting the result you're getting. It returns "Hello, World".

But if you want to trim a string you can use this code:

var s = "  Hi ";

s = s.replace(/^\s*/, "").replace(/\s*$/, "");

console.println(s.toSource()); // returns (new String("Hi"))

I don't know which script you're referring to. And please don't "hijack" someone else's thread for your questions...

If you want to contact me privately you can do so by sending me a message here, or via email (try6767 at gmail.com).

Is that a threat? You still owe me for that development, if I remember correctly. At any rate, let's discuss it privately, as it's really not relevant for the other people on this forum.

In relation to your answer, I got to messing around with my program, and found that trimming the white-space from a string before pushing it into an array worked very well
