React Js Render Data to Form | Two way Binding
React Js Render Data to Form | Two way Binding:Reactjs is a popular JavaScript library for building user interfaces. Two-way binding is a feature that synchronizes data between a component's UI elements and its state. When the state changes, the UI updates automatically, and vice versa. This bidirectional flow streamlines development and ensures that changes made by the user are reflected in the application's state, and changes in the state update the UI instantly. React simplifies this process through its virtual DOM, optimizing performance and providing a seamless user experience.

How to achieve two-way binding in Reactjs when rendering data to a form?
The provided code is a ReactJS application that renders data to a form using two-way binding. It initializes a state variable 'formValues' with some pre-defined data. Each input field is associated with a property from the 'formValues' object, and any changes in the input fields are reflected back to the state. When the "Submit" button is clicked, the current form values are logged to the console. Two-way binding enables real-time synchronization between the form and state, ensuring that any changes are immediately updated in both directions.

<script type="text/babel">
const { useState } = React;
const data = {
seo_title: 'React Js',
seo_description: 'React Js is a frontend framework',

code: 'Code',
bottom_desc: 'This is Bottom Desc'
};
function App() {
// Create a state variable for all input values as an object
const [formValues, setFormValues] = useState(data);
// Handler function to update the form values
const handleChange = (event) => {
const { name, value } = event.target;
setFormValues((prevValues) => ({ ...prevValues, [name]: value }));
