如何更新es6数组中的元素？

Question

I've an array of objects and I want to modify a property in the object.

I know we can remove the object using splice function.Is the only option to remove and add it back?

Answer 1

You have to modify it directly (assuming You know index)

YourArray[index].ObjectProperty = YourValue

It does not make any difference if it's ES6 or not

Answer 2

如果您只需要修改对象中的prop，则无需将其从数组中删除。

arr[2].prop = newValue;
