What is the difference between HTML and React event handling?

In HTML, the attribute name is in all lowercase and is given a string invoking a function defined somewhere:

<button onclick="handleClick()"></button>

In React, the attribute name is camelCase and are passed the function reference inside curly braces:

<button onClick={handleClick} />

In HTML, false can be returned to prevent default behavior, whereas in React preventDefault has to be called explicitly:

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

React:

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

Note: HTML uses lowercase, React uses camelCase.
