var arr = [1,2,3,4,5,6,7,8,9,10];push()
向数组的末尾添加一个或更多元素，并返回新的长度。
console.log(arr.push(11)); // 11
console.log(arr); // [1,2,3,4,5,6,7,8,9,10,11]pop()
删除并返回数组的最后一个元素
console.log(arr.pop()); // 11
console.log(arr); // [1,2,3,4,5,6,7,8,9,10]unshift()
向数组的开头添加一个或更多元素，并返回新的长度。
console.log(arr.unshift(0)); // 11
console.log(arr); // [0,1,2,3,4,5,6,7,8,9,10]shift()
删除并返回数组的第一个元素
console.log(arr.shift()); // 0
console.log(arr); // [1,2,3,4,5,6,7,8,9,10]
