How to use Events in ReactJS ?

Using Events is React js is very similar to handling event on DOM elements.The difference is only in syntax like.

1. The name of event is React js is always in camelCase.
2. With JSX you pass a function as the event handler, rather than a string.

Lets understand by an example:

// In HTML
<button onclick="activateAccount()">
  Activate Account
</button>

//In React
<button onClick={activateAccount}>
  Activate Account
</button>

Another difference is that in React js you cannot return false to prevent default behavior in React. You must call preventDefault explicitly. Read more from https://facebook.github.io/react/docs/handling-events.html
