Events

In React, you can handle events (like clicks, form submissions, and state changes) in a similar way to how you would in pure JavaScript, but with some important differences. React uses the Synthetic Event system, which means events are normalized to work the same way across all browsers.

Event Handling:

  • Events are handled using JavaScript functions.
  • In React, event names are written in camelCase, such as onClick, onChange, etc.
  • The default behavior of events can be prevented by using event.preventDefault().

Example of event handling:

              {`import React from "react";
      
              function Button() {
                const handleClick = () => {
                  alert("Button clicked!");
                };
      
                return (
                  <button onClick={handleClick}>Click me</button>
                );
              }
      
              export default Button;`}
