Object.keys()

Object.keys(obj) / Object.keys(arr)

let abc = {a: "a", b: "b", c: "c"};
console.log(Object.keys(abc));
// (3) ["a", "b", "c"]

let xyz = {x: "xxx", y: "yyy", z: "zzz"};
console.log(Object.keys(xyz));
// (3) ["x", "y", "z"]

// array like object with random key ordering
let anObj = { 100: 'a', 2: 'b', 7: 'c' };
console.log(Object.keys(anObj)); 
// ['2', '7', '100']

// 类数组 对象, 随机 key 排序 
let anObj = { 100: 'a', 2: 'b', 7: 'c' }; 

console.log(Object.keys(anObj)); 
// ['2', '7', '100']

/* getFoo 是个不可枚举的属性 */

Array.some() 实现的是非贪心算法(Regex: Regular Expression)，只要找到一个 true 就立即返回，不再向后面搜索了！
