The Quick Byte
One coding tip because you’re technical after all

This week’s coding challenge:

This week’s tip:

In React's useEffect hook, you can leverage the cleanup function to handle side effects that need proper teardown, such as WebSocket connections, event listeners, or subscriptions. The cleanup function runs before the component unmounts and before re-running the effect if dependencies change.

Wen?

• Resource Management: When dealing with subscriptions, connections, or timers that need to be properly disposed of to prevent memory leaks.

• Event Listener Cleanup: In scenarios where you're adding DOM event listeners that should be removed when the component unmounts.

• Real-time Connection Handling: When managing real-time connections like WebSockets or Server-Sent Events that need proper closure.
