🚀 React Developers Can you answer this tricky question? This looks simple, but it tests deep understanding of React’s rendering cycle, batching, and hooks. 👉 Many devs say “it increases count by 1,” but React will actually re-render endlessly. ✅ Why? Because the effect depends on count, and inside the effect we update count. Each update triggers the effect again, causing an infinite loop. #reactjs #frontenddevelopment #javascript #reacthooks #reactinterview #webdevelopment #nextjs #reacttips #frontendengineer #seniorfrontend #programming #womenintech #softwaredevelopment #developers #codingtips
Yes, this will cause an infinite loop. Since count is in the dependency array and we are updating count inside useEffect, every state update triggers a re-render, which re-runs the effect again.
useEffect hook will run after every render of the component. The code imside setCount updates the state variable count. Updating a state variable causes the component to re-render.
No whenever cout will change that time only this useEffect work
Yes, this will run infinite loop , useEffect hooks will run every render so count value will continuously change and setCount inside the useEffect again rerender
It will rerender not because of use effect but due to useState . So This re-render triggers the useEffect again, resulting in an infinite loop of updates and renders
Native fire! 🔥 This highlights the power of understanding dependencies in the useEffect hook. It's not just about adding variables; we must ensure each update is intentional to avoid re-renders. Classic example of React magic! 🔄
Use OpenAi api and fetch and use this same thing
Yes👍
It will cause an infinite rerender loop. useEffect depends on count, and inside the effect we update count Each update triggers a re-render, which runs the effect again and the cycle never stops. Updating a dependency state inside the same useEffect without a condition leads to an infinite loop.
