React Js Get Element by Id
React Js Get Element by Id :In ReactJS, the common approach to accessing elements in the Document Object Model (DOM) is through its virtual DOM abstraction. Instead of directly using document.getElementById, React encourages manipulating the DOM indirectly by managing components' states and rendering based on data changes. This promotes a more efficient and maintainable approach, minimizing direct DOM interaction. React's declarative nature allows developers to define how the UI should look based on data, abstracting away direct DOM access for a more predictable and scalable application structure.

How can you Get Element by ID using React js?
In this React.js code, a functional component called App is defined. Inside this component, there's a function called updateElement that gets an HTML element by its ID ('myElementId') using document.getElementById. If the element exists, it updates its content to 'Updated content' and changes its text color to red.
The App component renders a container with an initial div element having the ID 'myElementId', some introductory text, and a button. When the button is clicked, the updateElement function is invoked, demonstrating how to interact with the DOM (Document Object Model) within a React component. This code showcases a simple example of mixing React with traditional DOM manipulation.

In this React.js code, we use the useEffect hook to fetch an HTML element with the ID "myElementId" after the component has rendered. If the element exists, we access its content and log it to the console. This ensures that we interact with the DOM safely within the React component. The component renders a container with a title and a paragraph with the specified ID.
