Benchmark: Map vs Object UUID Key/Value

Script Preparation code:

var uuid = crypto.randomUUID();
var i = 0, count = 500, a;
a = crypto.randomUUID();

Tests:

Map
var map = new Map(); map.set(uuid, a); for (i = 0; i < count; i++) { map.set(a, crypto.randomUUID()); a = map.get(a); }
Obj
var obj = {}; obj[uuid] = a; for (i = 0; i < count; i++) { obj[a] = crypto.randomUUID(); a = obj[a]; }
