How to avoid binding the same variable to multiple copies of the component?

Question

JavaScript

The situation is the following. We are talking about Vue JS 2.
I need all copies of the componentX component to react to changes in the testArray array , but I did not find a way other than creating a binding via v-bind of the component property (prop) to the testArray variable . And the model of communication between components does not seem to imply anything else.
It turns out that I have about 100 copies of components with constant binding to the same variable. Will this load the system a lot and is it possible to somehow optimize this madness?
I would be grateful for help.

Answer 1

I found a solution in the form of a ref option , through which you can access all child components. Very comfortably.
