React Context is a tool for managing global state without props drilling, allowing components to share data between each other without passing props down manually. It reduces code complexity and makes it easier to maintain.
React Context can lead to performance issues if not optimized correctly. To improve performance, use memoization by storing the results of expensive function calls with `useMemo()`, so they don't have to be repeated on every render. This technique stores complex objects or functions computed previously, reducing unnecessary re-renders and improving application responsiveness.
