在数组中的对象上调用方法的功能方法

Question

I would like to call a method which takes no arguments and returns nothing, on each Object in an Array of homogenous objects, without using a for loop like this:

for (let i = 0; i < list.length; i++) {
    list[i].someMethod();
}

I've looked at using Array.forEach (and discounted Array.map ), tried passing the method name as a string, and by using call and grabbing the prototype method from one of the objects, as well as reading around the area on various websites.

I don't see a clean way to do it, such that every invocation is bound to the correct this . Can someone point out what blindingly obvious technique I've overlooked?

Answer 1

使用匿名函数作为forEach的回调，并像往常一样调用该方法： list.forEach(function(o) { o.someMethod(); });
