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

If you think all those prototype definitions, array creations, and join operations are overkill, just use a single line code where you need it. String S repeating N times:

for (var i = 0, result = ''; i < N; i++) result += S;
