Food for Thought
A mindset, an example, and an action item to start the week

"To handle yourself, use your head; to handle others, use your heart."

Eleanor Roosevelt

Mindset: Approach challenges with both logic and empathy to find the best solutions.

Example: Zappos, the online shoe retailer, is known for its customer-centric culture, where employees are encouraged to use their hearts to deliver exceptional service.

Action: Reflect on a recent interaction - did you use both your head and heart? Identify one way to improve.

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 utilize the cleanup function to prevent memory leaks and handle component unmounting gracefully. The cleanup function runs before the effect runs again and when the component unmounts, making it crucial for managing subscriptions, event listeners, or any ongoing processes.

Wen?

  • WebSocket Connections: Essential when dealing with real-time data streams or WebSocket connections that need to be properly closed when the component unmounts.

  • Event Listener Management: Critical for removing event listeners attached to window or document objects to prevent memory leaks and unexpected behaviors.

  • Timer Cleanup: Necessary when using setInterval or setTimeout to ensure timers are cleared and don't continue running after component unmounting.
