在可迭代对象(包括 Array,Map,Set,String,TypedArray,arguments 对象等等)上创建一个迭代循环,调用自定义迭代钩子,并为每个不同属性的值执行语句。 可以看到它支持的种类非常多,最常用的就是Array和arguments了,但是注意虽然支持这么多并不能像for...in...用于普通Object的迭代。上面我们不推荐for...in...应用于...

In this tutorial, we will show you how to loop through an array of objects and make a loop with js foreach element with class. We will also use tryit to edit and run the code online. You can make any changes to the code as you want and see the results in
4 ways to convert an array-like object, such as HTMLCollection and NodeList, to JavaScript arrays for access to array methods like the forEach loop.
