JavaScript React Basics (retired) Stateful Components Creating a Component Class

React.createClass or class ... extends React.Component???

I'm reading react.js documentation and they use class ... extends React.Component this way of creating a class... Is the same ? I have to learn that?...

What you are referring to is JavaScript ES6, it's quickly becoming the standard (and good practice) to write React in ES6 however, it's still optional to do this. If you have trouble understanding ES6 then read this on the official documentation....

It's worth diving into ES6 as it certainly has its advantages and makes things slightly more "cutting edge".

Additionally, don't try and use ES6 without Babel as it is still fairly new and is compiled by Babel in order to work.
