JavaScript Array push()

陣列 (array) 的 push() 方法用來新增元素到陣列最後面。

語法：

ary.push([element1[, ...[, elementN]]])

push() 方法會返回陣列新的長度。

用法：

var fruits = ['Apple', 'Banana'];

fruits.push('Orange');

// 輸出 ["Apple", "Banana", "Orange"]
console.log(fruits);

var sports = ['soccer', 'baseball'];
var total = sports.push('football', 'swimming');

// 輸出 ["soccer", "baseball", "football", "swimming"]
console.log(sports);

// 輸出 4
console.log(total);
