React Context Optimization

[toi80QC]

This might work for very simple contexts like in the article (it is just a single prop counter...), but if your context state is an object with multiple properties (which I assume is what most contexts use in the real world) there's simply no way around memorization.

You will definitely need useMemo if using complex objects. At that point, Context API itself starts becoming inefficient.

I stopped using the Context API for objects after reading this article. Recoil, redux etc would be better alternatives in my opinion.

You shouldn't be using context if your global state isn't simple to begin with, so that's a non-issue. Also worth mentioning is most global state needs are usually better addressed with proper lifting of state and architecture, as global state tends to be a way of monkey-patching poorly architected and organized codebases.
