React is a popular JavaScript library used for building user interfaces. One of the key features of React is its ability to manage state and re-render components efficiently. In some cases; however, re-rendering components can be computationally expensive and slow down the user interface. This is where the useMemo() hook comes in handy.
What Is useMemo() Hook?
The useMemo() hook is a built-in React hook that allows you to optimize the performance of your React application by memoizing expensive computations. Memoization is the process of caching the results of a function call based on its input parameters. This means that if the input parameters of a function remain the same, the function will return the same output without re-executing the computation.
