Reselect is a popular JavaScript library for creating memoized selectors in Redux applications. It provides a simple and efficient way to compute derived data from the Redux store, ensuring that expensive computations are only performed when necessary.

With Reselect, you can define selectors that take input from the Redux store and return a calculated value. These selectors are memoized, meaning that if the input values haven't changed, the previously computed result is returned instead of recomputing it. This can greatly improve performance by avoiding unnecessary computations and re-rendering of components.

Compared to manually computing derived data in Redux, Reselect offers a more organized and efficient approach. It helps to keep the state management code clean and maintainable, especially in large-scale applications with complex data dependencies.

Reselect is actively maintained and widely used in the Redux ecosystem. It has become a standard tool for optimizing Redux selectors and is recommended by the Redux documentation.
