You can access the characters in a string in two ways: 1. Using Indexes One way is to treat strings as an array and access the character at the specified index. For example, let message = "hello"; // use index 1 to access // 2nd character of message console.log(message[1]); //...
表示“一个布尔值,如果是true,则意味着对象应该用Array.prototype.concat()打平其他数组元素” ES6 中的Array.prototype.concat() 方法会根据接收到的对象类型选择如何将一个类数组对象拼接成数组实例 覆盖Symbol.isConcatSpreadable 的值可以修改这个行为 数组对象默认情况下会被打平到已有的数组, false 或假值会导致...
In JavaScript, by usingsplit()method we can split a string into an array of substrings and returns the new array. This method does not change the original string. EXAMPLE 1:Spliting a string into an array (Each value is sperated by comma). ...

5. 数组对象 5.1数组的创建 之前提到过数组的创建方式 字面量 new Array() 5.2 检测是否为数组的两种方式 之前提到过翻转数组,如下: 调用函数的时候传入的实参必须是数组的形式,若输入的实参不是数组则会出现错误,因而需要对函数进行优化,判断传入的实参是否为数组。检
