Our expert team is currently recording the visual guide for Events in React.
The Core Concept
Handling events in React is very similar to handling events in standard HTML DOM, but with a few syntax differences. React events are named using camelCase (like `onClick` instead of `onclick`). Furthermore, instead of passing a string to the event handler, you pass a JavaScript function. This allows you to execute complex logic or update component state when a user interacts with your application.

Code & Implementation
function AlertButton() {
const handleClick = (event) => {
// Prevent default behavior if needed (e.g., in forms)
// event.preventDefault();
alert('Button was clicked!');
};
return (
<button onClick={handleClick}>
Trigger Alert
</button>
);
}Expected Output
