The useMemo Hook
Explore how to enhance React app efficiency by using the useMemo Hook to memoize costly calculations. Understand when and how to apply useMemo to minimize re-computation during state updates. Practice optimizing list filtering, fibonacci calculations, and salary computations to improve component performance.
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.
