How can you add a CSS class to an element by its ID in a Reactjs application?
In this React.js code snippet, a functional component called "App" is defined. It contains a function, "addClassToElement," which adds a CSS class called "my-new-class" to an HTML element with the ID "myElement" when a button is clicked. The component renders a container with a title, a div element with the specified ID, and a button. When the button is clicked, the "addClassToElement" function is executed, and if the element with the ID "myElement" exists, it adds the class to it. This allows for dynamic manipulation of the element's styling in response to user interaction within a React application
