I've been working professionally with React for more than 8 years and I compiled all my knowledge into 100+ infographics and 70+ video tutorials just like this one. Check them out ↓

“When something breaks, be transparent, own it, fix it. And it's really about how you respond to it.” @WilHarm3 (@craft_ventures) emphasizes the importance of transparency and responsiveness when things go wrong. Watch the episode here:

Good advice, but in this case you might not need an useEffect. Like this article of official documentation said, a useEffect is to synchronize external state (API, storage, DOM) with internal state of React.

Here,understanding the concept of passed by value and passed by reference shines. When we put an passed by reference item into the dependency array, it makes the useEffect to re-run on reach re-render. Good point 👍

if you use const {userId} = params everything should be the same no?

Have you tried using primitive keys in your useEffect dependencies? It can really help avoid unnecessary re-renders. I’ve seen it make a big difference in performance.

New tool that smooths out curves horizontally instead of vertically, or in other words smooths out the time Works on selected keys and multiple objects at a time. The smoothing strength is adjustable Can be useful for baked keys after retiming (such as mocap or space switching)

❌ Don't pass props to multiple nested components in React. ✅ Instead use libraries like react-query to better handle server state.
