React Refs and the useRef Hook - Introduction to React #6
This video explores how to use refs in React. Refs are initialized with the useRef hook and they can have an initial value. The ref object has a current property that can be updated and read. The value of the ref variable is preserved between re-renders. Usually refs are used to store references to elements, control media playback or control animations, but that's not their only use. We explore two examples - focusing an input and building a stopwatch.
