Script Preparation code:

var a = Array(1000).fill(null).map((a, b) => b);

Tests:

Unique Array
var b = []; a.forEach(x => { if (a.indexOf(x) < 0) a.push(x); }); a.map(x => x);
Set
var c = new Set(); a.forEach(x => c.add(x)); var b = Array.from(a); b.map(x => x);
Arr 2
var b = []; a.forEach(x => { if (a.indexOf(x) === -1) a.push(x); }); a.map(x => x);
