In the case of React-Redux, we do a _lot_ of work to check the derived values you've extracted from the Redux store, and prevent your own component from re-rendering unless those values have changed.
See my post "The History and Implementation of React-Redux" for more details:

- sorahn 8y agoSomehow the codebase I recently took over has managed to mess this up. Every time any part of the state tree anywhere changes, the whole app re-renders. I’m trying to track down why this is an issue, but so far I haven’t had much luck. Do you know of any tools that can assist with this specific kind of debugging?
