Question

我在这里缺少什么？不应该这只是推动＆＃39; hi＆＃39;进入[4]，而不是用名为＆＃39; push＆＃39;？

的键命名

<script>
    Array = ["Banana", "Orange", "Apple", "Mango"];
    Array.push = ('hi');
    console.log(Array);
</script>

Answer 1

你应该这样做 -

    var sampleArr = ["Banana", "Orange", "Apple", "Mango"];
    sampleArr.push('hi');
    console.log(sampleArr );

Answer 2

正确的方法是：

var arr = ["Banana", "Orange", "Apple", "Mango"];
arr.push('hi');
console.log(arr);

Answer 3

您的语法不正确。

var array = ["Banana", "Orange", "Apple", "Mango"];
array.push("hi");
