Welcome to my blog post about Learn and implementing useRef in React. React is a JavaScript library for building user interfaces, and useRef is one of the most commonly used tools for creating and manipulating DOM elements.
In this post, I will take you through the basics of useRef and demonstrate how to use it in your React applications. We will explore the different ways to use and leverage useRef in React, and discuss why you might want to use it over other methods. Finally, I will provide you with some tips and tricks to make the most out of Implementing useRef in React.

Introduction
React is a popular JavaScript library for building user interfaces, and useRef is one of its most useful features. useRef allows developers to create and access references to elements within a React component. It provides an easy way to access and manipulate DOM elements without having to use a JavaScript library like jQuery. By leveraging the power of useRef, developers can create powerful and efficient web applications that look and function great.
What is useRef?
useRef is a React hook that returns a mutable reference object whose current property is initialized to the passed argument. This reference object can be used to store references to DOM elements, React components, or other JavaScript objects. The reference object is a simple object with a single property – current – that stores the object it was passed when the hook was called.
When to use useRef?
useRef is a great tool for developers who need to access and manipulate DOM elements or React components within a React component. This can be especially useful for creating complex user interfaces with animations and interactive components. It can also be used to store references to other JavaScript objects, such as functions, HTML elements, and React components.
How to use useRef?
Using useRef is very simple and straightforward. The following is an example of how to use it. First, we need to import useRef from React:
import { useRef } from 'react';
Then, we create the reference object:
const myRef = useRef(initialValue);The initialValue argument is optional, but it is recommended to provide it for easier debugging.
Once the reference object is created, we can access and manipulate its current property. For example, we can use it to store a reference to an HTML element:
const myDiv = useRef(null);
We can then use this reference to access the DOM element and manipulate it:
myDiv.current.style.backgroundColor = 'red';Conclusion
React’s useRef hook is a powerful tool for developers who need to access and manipulate DOM elements or React components within a React component. It provides an easy way to access and manipulate DOM elements without having to use a JavaScript library like jQuery. By leveraging the power of useRef, developers can create powerful and efficient web applications that look and function great.
