I'm no expert, but mouse drag events in React are fairly simple to get working performantly, even without understanding how it works under the hood. There are even many libraries that provide functionality, all without it running 'like a pig'.

Yes, but I didn't want to use a library because I was doing something a bit out of the usual case.

I do like understanding my code as much as possible. So I was choosing between: 1. Understand React better, and reading about the "React" way to use these mouse events. 2. Doing it in VanillaJS

My point was not to use a library, but that many others have implemented functionality in libraries without performance decreases. Granted, your use case may be special to the point where vanilla JS is better, but given how many libraries are out there, as well as how many may simply be poorly implemented yet still work fast, makes me wonder what you were indeed doing.

The great thing about the "React" way of doing things is that it's just the JavaScript way of doing things.

React can be summed up entirely as: "a function that takes in props and returns rendered HTML". It is not a framework. There is no black magic. There are no idioms. There are no batteries included.

Anything else you do with it beyond that is entirely up to you.

That’s a bit too strong imo. There is magic, and it can generally be found in implicit re-render conditions.

"Rules of hooks" is a thing.
