Script Preparation code:

var fooArr = [];
for(var i=0;i<10000;i++) {
  fooArr.push(i);
}

Tests:

Set duplication
var set = new Set(fooArr);
includes
var barArr = [] for(var i=0;i<fooArr.length;i++) { if (!barArr.includes(fooArr[i])) barArr.push(fooArr[i]) }
hasmap
var hashmap = new Map(); var barArr = [] for(var i=0;i<fooArr.length;i++) { if (!hashmap.has(fooArr[i])) { barArr.push(fooArr[i]); hashmap.set(fooArr[i], true); } }
