Learn ReactJs. Part 3 - you don’t need useState hook 🤯😱

Let me explain. useState is one the used and useful hooks, but unfortunately we tend to overuse it. It is amazing hook for managing state, but it is not an answer for everything.

✅ If you just want to remember some value and not to forget about that during re-renders, without rendering it to user -> useState is not meant for it, better choose useRef.

✅ If you have data in the state, but you want to modify it and get new values from it -> you don’t need to put keep that new values in the new useState object, simply create new variable and operate with that.

✅ If the component receives props and you want to get some specific data from it -> don’t put it in the state immediately, because very often you just don’t need it. As I mentioned before, just create a new variable and use that.

Keep coding and have fun 🤩

useSate is the most popular and the most used hook, but it doesn’t mean, that you always need it.

useState is meant for managing state, for redrawing component depending on user’s interactions. If you want to remember something, but you are not rendering it, than you probably shouldn’t put it in the state. useRef would be the best option.
