React: State implementation guide as Expected When Using Multiple setState Calls in a Loop
I'm learning this framework and I'm stuck on something that should probably be simple. Hey everyone, I'm running into an issue that's driving me crazy. I'm stuck on something that should probably be simple. I'm working with an scenario in my React component where the state isn't updating as I expect it to when I call `setState` multiple times within a loop. I'm using React 17 and functional components with hooks. The following is my current implementation: ```javascript import React, { useState } from 'react'; const NumberIncrementer = () => { const [count, setCount] = useState(0); const incrementCount = () => { for (let i = 0; i < 5; i++) { setCount(count + 1); } }; return ( <div> <p>Count: {count}</p> <button onClick={incrementCount}>Increment</button> </div> ); }; export default NumberIncrementer; ``` When I click the 'Increment' button, I expect the count to increase to 5, but it only increments by 1. The reason seems to be that the `count` variable inside the loop is only capturing its initial value due to closure. I tried using the functional version of `setState` like this: ```javascript const incrementCount = () => { for (let i = 0; i < 5; i++) { setCount(prevCount => prevCount + 1); } }; ``` However, this still only results in a single increment when I click the button. I also checked the React documentation, but it doesn’t cover this specific case. I've verified that my component is not being re-rendered unnecessarily and that other parts of the state management are functioning correctly. Is there a better way to handle this situation to achieve the expected result? My development environment is macOS. Is there a better approach? My development environment is macOS. This is part of a larger service I'm building. Thanks in advance! This is part of a larger service I'm building. Am I missing something obvious? I appreciate any insights!
