useRef() is a React hook that returns a mutable ref object. A ref is a way to store a value that persists between renders and is not part of the component state. Unlike the state, changes to a ref do not trigger a re-render of the component. useRef Hook allows you to persist values between renders. It can be used to store a mutable value that does not cause a re-render when updated. It can be used to access a DOM element directly. useRef() only returns one item. It returns an Object called current. const count = useRef(0);
