var obj = {"one": true, "two": true, "three": true, "four": true, "five": true, "six": true, "seven": true, "eight": true, "nine": true, "ten": true};
var map = new Map([["one", true], ["two", true], ["three", true], ["four", true], ["five", true], ["six", true], ["seven", true], ["eight", true], ["nine", true], ["ten", true]]);

var has = map.has('ten');
Get from Array
var value = arr[9];
Has key in Array OLD
var has = arr.indexOf('ten') > -1;
Has key in Array NEW
var has = arr.includes('ten');
Has key in Set
var has = set.has('ten');
