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.
Handling forms in React can be complex and error-prone, but using libraries like Formik or React Hook Form can simplify the process. Formik is established with features like declarative API, automatic state management, validation integration, and error handling, but has performance issues and compatibility problems. React Hook Form is newer and lighter, making it suitable for large-scale applications, but may have a steeper learning curve.
