How to check for collisions in threejs?

Question

JavaScript

Hello! I want to know how to quickly check for collisions in threejs between a large number of objects. This is necessary so that the hero can walk around the map there and check for bullets hitting him. It seems that there is a render, but I don’t know how to efficiently check collisions. (I also want to note that I have very poor knowledge of the English language)

If you want to develop something serious, you need English.
