How can I optimize the performance of my React app using TypeScript?

You can optimize performance by using techniques like memoization, lazy loading, and code splitting. Would you like details on any specific technique?

What is memoization and how can I implement it?

Memoization is a technique to cache the results of expensive function calls. In React, you can use the useMemo and useCallback hooks to memoize values and functions.

Can you give me an example of using useMemo?

Sure! Here's a simple example:

const memoizedValue = useMemo(() => computeExpensiveValue(a, b), [a, b]);

This will only recompute the value when a or b changes.

What about lazy loading?

Lazy loading allows you to load components only when they are needed. You can use React's React.lazy and Suspense for this purpose.
