static const int kPreallocatedArrayElements = 4; // 这里可以看到数组默认初始大小为4 }; 注释上看到 数组分为两种实现模式 快数组存储结构是 FixedArray时,length<= elements.length();请注意:push和pop可以用于增加和缩小数组 慢数组存储结构是HashTable(哈希表)时,数组下标作为key; 在v8实现的源码中fast模式...

var numberOfElements = myArray.length; 在前面的示例中,在向数组中添加数据之前,您通过编号显式地调出了每个元素。如果你只是想给下一个打开的槽添加一些东西,数组对象有一个名为push的方法。这也是确保元素的编号顺序没有间隔的好方法。let nameArray = []; nameArray.push("Norah"); nameArray.push("...
