useMemo Hook in React | Memoization in React | Optimisation Techniques

useMemo Hook is use to implement memoization in React components.
Memoization is a technique for performance optimization where result of expensive function get store in cache and for next calls, instead of executing the function again, it return the data from cache value - it drastically improve the performance.
In REact Components also we can get this with the help of useMemo hook, which is really effective for component performance but use it with proper use case, otherwise it can harm the performance as well :)

[@tushard3736]

that dependeny at 10:24 should be a primitive right , due to performance issues , because objects are compared by reference , something like users.length , or maybe useMemo and cache the users too , then you can pass the entire users into dependency?

[@rajranjan8984]

We can also apply usEffect hook instead of useMemo and pass dependency, what's different between using both
