How to call a method of a neighboring component from one component?

Question

Vue.js

The whole point is in the header. You need to call the method of the neighboring component

Answer 1

I don't understand Vue, but I have some experience in front-end development with other frameworks.
If you need to call a component's neighbor method, then you are most likely doing something wrong. But if you can't do without it, then you need to create a method in the parent component and pass it to the child. And the method in the parent will already call the neighboring one.
