Is there a JavaScript function that can pad a string to get to a determined length?

Question

I am in need of a JavaScript function which can take a value and pad it to a given length (I need spaces, but anything would do). I found this:

If you just want a very simple hacky one-liner to pad, just make a string of the desired padding character of the desired max padding length and then substring it to the length of what you want to pad.

Example: padding the string store in e with spaces to 25 characters long.

var e = "hello"; e = e + "                         ".substring(e.length)

Result: "hello "

If you want to do the same with a number as input just call .toString() on it before.
