Refs provide a way to access DOM nodes or React elements created in the render method.
They should be avoided in most cases, however, they can be useful when we need direct access to DOM element or an instance of a component.
There are a few good use cases for refs:
Managing focus, text selection, or media playback.
Triggering imperative animations.
Integrating with third-party DOM libraries.
Refs are created using React.createRef() and attached to React elements via the ref attribute. Refs are commonly assigned to an instance property when a component is constructed so they can be referenced throughout the component.
