JavaScript: Repeat string

I wanted to build a string of 20 repeating characters. This function makes it really easy:

String.prototype.repeat = function(num) {
    return new Array(num + 1).join( this );

Now I can write:

var separator = "=".repeat(20);

Thanks you so much for the this function. Not only did I need it, but I learned from it.
