React.js: how to pass data from one module to another?

Question

JavaScript

Hello, such a question: the application is based on react, there is a main module Main , into which module A and module B are connected .
Module A requests data from the server, receives it and filters it, and then adds it to the array.
Question: how can I transfer data (array) from module A to module B if they are not interconnected, that is, module A and module B are loaded into the Main module and drawn in it?
As an option: make a request in the Main module itself , process this data and pass it to module B? But it seems to me that this is not true, because the data that belongs to module A is better to process in it?
