React Tutorial In Hindi #42: React useRef Hook | React JS Tutorial For Beginners To Advanced

React Tutorial In Hindi, In this video we learn about React useRef Hook. In React, "useRef" is a Hook that allows you to create a mutable reference to an element or a value that persists across renders. It is commonly used for accessing and interacting with DOM elements, managing focus, and storing values that should not trigger a re-render when they change.

React JS Tutorial for Beginners to Advanced, The primary use cases for useRef are:
Accessing DOM elements: You can use useRef to get a reference to a DOM element, like changing its style, adding event listeners, or triggering imperative functions.
Storing mutable values: Since the ref object persists across renders, you can use it to store values that need to be accessed and updated without triggering re-renders.
Caching expensive calculations: If you have a computation that is costly in terms of performance and doesn't depend on the component's state or props, you can use useRef to store the result of the computation and reuse it across renders.
