useCallback is a hook in React that is used to memoize functions, especially callback functions, in order to prevent unnecessary re-creations of those functions on each render. This can help in optimizing performance, particularly in scenarios where child components receive functions as props.
Here's an explanation of how useCallback works:
In React, functional components can re-render whenever their state or props change. If a function is defined inside a component, it is recreated every time the component renders. This can be inefficient, especially when passing functions as props to child components. useCallback addresses this issue by memoizing the function, meaning it returns the same function instance unless the dependencies specified in the dependency array change.
