JavaScript Array vs new Array区别

Posted 2020-08-02 5Mi17

　　规范说明　

　　When Array is called as a function rather than as a constructor, it creates and initialises a new Array object. Thus the function call Array(…) is equivalent to the object creation expression new Array(…) with the same arguments.

　　当数组作为函数调用而不是构造函数调用时，它会创建并初始化一个新的数组对象。因此当Array(...)和new Array(...)接收同样的参数时，它们是相同的。
