useCallback

Author

useCallback is a Hook that returns a memoized version of the passed function. It is used to prevent functions from being recreated on each render, which can improve performance when passing functions to child components.

useCallback example:

          {`import React, { useCallback, useState } from "react";
          
          function MyComponent() {
            const [count, setCount] = useState(0);
            
            const increment = useCallback(() => {
              setCount((prevCount) => prevCount + 1);
            }, []);
            
            return (
              

Count: {count}

); } export default MyComponent;`}
