Refs provide a way to access DOM nodes or React elements that I create in the render method. Unlike traditional methods like document.getElementById, refs offer a more React-friendly approach to handle DOM interactions.

Refs are not a silver bullet. They are powerful when used correctly, but they can also be a source of confusion. For instance, accessing a ref during rendering can lead…
