useRef Hook (Full Course, Part 4 of 6) with Blues Wireless Staff Software Engineer, Paige N.

React Hooks promise to eliminate the difficulties of sharing state without writing class-based components. The challenge is that Hooks do away with the lifecycle methods and class-based semantics of state management that many React developers were familiar with. Learning to use both the in-built React Hooks and implement your own Custom Hooks, however, is essential to unlock the code reuse and many other advantages that this update offers for any React-based project. While there are some resources for learning React Hooks, many have incomplete coverage. Paige fully details useState, useEffect, useRef, useContext, and Custom Hooks in this series (links below).
