React has changed, your Hooks should too

Matt Smith:

React Hooks have been around for years, but most codebases still use them the same way: a bit of useState, an overworked useEffect, and a lot of patterns that get copy-pasted without much thought. […]

Before reaching for useEffect, ask yourself:

• Is this driven by something external (network, DOM, subscriptions)?
• Or can I compute this during render?

If it’s the latter, tools like useMemo, useCallback, or framework-provided primitives will make your component a lot less fragile.
