Repeat String - Javascript

Question

What is the best or most concise method for returning a string repeated an arbitrary amount of times?

The following is my best shot so far:

function          


        

Answer 1

Recursive solution using divide and conquer:

function repeat(n, s) {
    if (n==0) return '';
    if (n==1 || isNaN(n)) return s;
    with(Math) { return repeat(floor(n/2), s)+repeat(ceil(n/2), s); }
}
