Array.prototype.repeat seems like a logical dual to String.prototype.repeat:
http://wiki.ecmascript.org/doku.php?id=harmony:string.prototype.repeat
Implementation:
Array.prototype.repeat = function (times) {
var result = [];
var len = this.length;
var resultLen = len * times;
for(var i = 0; i < resultLen; i++) {
result.push(this[i % len]);
}
return result;
}
In use:
$ [1,2,3].repeat(3)
[ 1, 2, 3, 1, 2, 3, 1, 2, 3 ]
