Introduction to useRef Hook
The useRef hook is a powerful feature in React that lets you create a mutable reference to a value or a DOM element.
Unlike state, changing a useRef value does not cause the component to re-render, making it useful for storing values that don't affect UI output.
“useRef is like a box that can hold a mutable value in its current property.”
