Benchmark: Array.includes vs String.includes vs Object Hashmap vs Set Large

Script Preparation code:

var testArray = ['foo', 'a','b', 'c','d','e','f','g','h','i','j', 'k', 'l','m','n' ,'bar'];
var testString = testArray.join(',');
var objectHash = testArray.reduce((acc, key) => {acc[key] = true; return acc;},{});
var testSet = new Set(testArray);

Tests:

Array.includes
const testStrFirst = 'foo'; testArray.includes(testStrFirst); const testStrSecond = 'bar'; testArray.includes(testStrSecond); const testStrNotMatch = 'baz'; testArray.includes(testStrNotMatch);
String.includes
const testStrFirst = 'foo'; testString.includes(testStrFirst); const testStrSecond = 'bar'; testString.includes(testStrSecond); const testStrNotMatch = 'baz'; testString.includes(testStrNotMatch);
Object Hash-map
const testStrFirst = 'foo'; objectHash[testStrFirst]; const testStrSecond = 'bar'; objectHash[testStrSecond]; const testStrNotMatch = 'baz'; objectHash[testStrNotMatch];
ES6 Set
const testStrFirst = 'foo'; testSet.has(testStrFirst); const testStrSecond = 'bar'; testSet.has(testStrSecond); const testStrNotMatch = 'baz'; testSet.has(testStrNotMatch);
