<button onclick=’activateLasers()’>

Whereas in React it follows camelCase convention:

<button onClick={activateLasers}>

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

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

Whereas in React you must call preventDefault() explicitly:

function handleClick(event) {

event.preventDefault()

console.log(‘The link was clicked.’)

}
