var a = [];
for (var i = 0; i < n; i++) {
  a.push(i);
}
ready
While set backwards
var n = 10000;
var b = n;
var a = [];
while (b--) a[b] = b;
ready
While set forwards
var n = 10000;
var b = 0;
var a = [];
while (b++ < n) a[b] = b;
ready
For set
var n = 10000;
var a = [];
for (var i = 0; i < n; i++) {
  a[i] = i;
}
