This is a more optimized version of the first script - here we arecaching the length of the arrayin a variable - so javascript will not have to find the length every time. This works only if thelength of the ar
async/await in for loop是指在JavaScript中使用async/await语法结合for循环进行异步操作的一种方式。 在传统的JavaScript中,使用回调函数或Promise来处理异步操作,但这种方式会导致回调地狱或过多的.then链,使代码难以阅读和维护。而async/await语法则提供了一种更简洁、直观的方式来处理异步操作。
JavaScript supports different kinds of loops: for- loops through a block of code a number of times for/in- loops through the properties of an object for/of- loops through the values of an iterable object while- loops through a block of code while a specified condition is true ...

一个广泛使用的类库 Prototype 就扩展了原生的 JavaScript 对象。因此,当这个类库被包含在页面中时,不使用 hasOwnProperty 过滤的 for in 循环难免会出问题。总结推荐总是使用hasOwnProperty。不要对代码运行的环境做任何假设,不要假设原生对象是否已经被扩展了。
