Benchmark: Object vs Set vs Map Existence Check

Script Preparation code:

var obj = {'k0': true, 'k1': true, 'k2': true, 'k3': true, 'k4': true, 'k5': true, 'k6': true, 'k7': true, 'k8': true, 'k9': true};
var s = new Set(['k0', 'k1', 'k2', 'k3', 'k4', 'k5', 'k6', 'k7', 'k8', 'k9']);
var m = new Map([['k0', true], ['k1', true], ['k2', true], ['k3', true], ['k4', true], ['k5', true], ['k6', true], ['k7', true], ['k8', true], ['k9', true]]);

Tests:

Object
let bool; for(let i = 0; i < 20; i++){ bool = !!obj[`k${i}`]; }
Set
let bool; for(let i = 0; i < 20; i++){ bool = s.has(`k${i}`); }
Map
let bool; for(let i = 0; i < 20; i++){ bool = m.has(`k${i}`); }
