The useMemo Hook

In modern React applications, optimizing performance is crucial to ensure smooth and efficient user experiences. One common issue is unnecessary computations that can slow down the app. This is where the useMemo hook becomes very valuable.

Understanding useMemo

The useMemo hook is used to optimize the performance of our application by memoizing the result of a computation. It returns a memoized value that only recalculates when one of its dependencies changes. This avoids unnecessary recalculations on every render, making our application more efficient.
