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

"Believe you can and you're halfway there."

Theodore Roosevelt

Mindset: Belief is the first step to any achievement. Adopt a mindset of possibility.

Example: Apple's early days, when Steve Jobs believed they could build a computer for the masses, despite naysayers.

Action: Write down one thing you believe you can achieve, and read it aloud each morning.

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

This week’s coding challenge:

This week’s tip:

In React, the useCallback hook can be optimized further by using a stable reference pattern with a ref to maintain function identity across renders while still accessing the latest state values.

Wen?

  • Performance Critical Components: When dealing with components that re-render frequently and pass callbacks to expensive child components or hooks like useEffect.

  • Real-time Updates: In scenarios where you need to maintain function stability while accessing the latest state values, such as debounced search functions or event handlers.

  • Memory-Intensive Applications: When working with large applications where unnecessary re-renders can significantly impact performance and memory usage.
