React Js Multiple Radio Button
React Js Multiple Radio Button:React.js provides a straightforward way to handle multiple radio buttons. First, you need to create a state variable to store the selected value.
Next, map over an array of radio button options, rendering each option with a unique key. For each radio button, set the checked attribute to the selected value in the state and update the state when a radio button is selected.
This way, only one radio button can be selected at a time, and the state holds the value of the selected radio button. Additionally, you can use the onChange event to trigger an action when the selection changes.

How can I implement multiple radio buttons in a React.js application?
This code snippet demonstrates the implementation of multiple radio buttons using React.js. It starts by importing the necessary dependencies and hooks from the React library. The main component, App, is defined using a functional component approach.
Inside App, the selectedOption state variable is declared using the useState hook, initialized as an empty string. The handleOptionChange function is used to update the selected option based on the user's input.
An array of options is defined, each containing a value and label. The options array is then mapped over, and for each option, a radio button is rendered with its corresponding label. The checked property of each radio button is determined by comparing the selectedOption state value.
Finally, a paragraph is rendered below the radio buttons to display the currently selected option. The entire component is rendered using ReactDOM.render and mounted on an HTML element with the id "app".
