What is the difference between HTML and React event handling?

Below are the few differences between HTML and React event handling, 1. In HTML, the event name should be in lowercase.

<button onclick="activateLasers()">

Whereas in ReactJS it follows camelCase convention,

<button onClick={activateLasers}>

2. In HTML, you can return false to prevent default behavior,

<a href="#" onclick="console.log('The link was clicked.'); return false"/>

3. Whereas in ReactJS you must call preventDefault explicitly,

function handleClick(e) {
      e.preventDefault();
      console.log('The link was clicked.');
}
