Struggling with state updates causing re-renders in my React component
I'm maintaining legacy code that Currently developing my first React application, I’ve hit a snag with how my component handles state updates. I'm using React 18 with functional components and hooks. The issue arises when trying to update the state based on the previous state. After watching a few tutorials, I implemented the following code: ```javascript import React, { useState } from 'react'; const Counter = () => { const [count, setCount] = useState(0); const increment = () => { setCount(count + 1); }; return ( <div> <p>Count: {count}</p> <button onClick={increment}>Increment</button> </div> ); }; export default Counter; ``` While this works fine for simple increments, I noticed that when I try to update the count using a function that relies on the current state, the updates don’t behave as expected. I attempted to refactor the increment logic like this: ```javascript const increment = () => { setCount(prevCount => prevCount + 1); }; ``` This change seemed to fix the issue when incrementing rapidly, but now I’m uncertain if I’m handling more complex updates correctly. For example, if I wanted to increment by a variable amount based on user input, would this still be the right approach? Here’s what I’m considering: ```javascript const incrementBy = (value) => { setCount(prevCount => prevCount + value); }; ``` I’m also wondering about performance implications when using a functional update versus setting the state directly. If there’s a lot of rapid state changes, might using `setCount` directly lead to performance issues? Any advice or best practices on managing state updates effectively in functional components would be greatly appreciated! The stack includes Javascript and several other technologies. The project is a application built with Javascript. Any pointers in the right direction?
