I like it, it indeed looks very logical, however it's a bit controversial
that we need to create temporary array object to get one that we want.
Function (not method) that returns generated array may make more sense,
currently I'm using something like that:
var slice = Array.prototype.slice;
Array.generate = function (length, fill) {
var arr, l;
length = length >>> 0;
if (arguments.length < 2) {
throw new TypeError("Cannot generarte an array without provided
fill.");
}
arr = slice.call(arguments, 1, 1 + length);
while ((l = arr.length) < length) {
arr = arr.concat(arr.slice(0, length - l));
}
return arr;
};
