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

From now on, the quick byte will also include a coding challenge from the excellent newsletter of John Crickett, here’s for this week:

Now for this week’s Byte:

The useMemo hook in React is a powerful tool for improving the performance of your application by memoizing expensive computations. It recalculates the memoized value only when one of its dependencies has changed, thus avoiding unnecessary recalculations on every render.

Wen?

• Computing Derived Data: Useful when you have expensive calculations that derive data from the component's props or state.

• Avoiding Unnecessary Renders: Essential in components with expensive child components or when passing down callback props to prevent unnecessary re-rendering.

• Performance Sensitive Situations: In scenarios where performance is critical and computation costs are high.

Why?

• Performance Gains: Prevents expensive operations from being run on every render, saving processing time and resources.

• Referential Equality: Ensures that child components receiving the memoized value do not re-render unless the value changes.

• Code Clarity: Indicates which parts of your component rely on expensive computations, improving code maintainability.
