XMLHttpRequest.send() accepts an optional argument for the request body. If the request method is GET or HEAD, the argument is ignored and request body is set to null.

// Use Gists to store code you would like to remember later on
console.log(window); // log the "window" object to the console

## React autobinding
Autobinding
React.createClass has a built-in magic feature that bound all methods to this automatically for you. This can be a little confusing for JavaScript developers that are not used to this feature in other classes, or it can be confusing when they move from React to other classes.

Therefore we decided not to have this built-in into React's class model. You can still explicitly prebind methods in your constructor if you want.

class Counter extends React.Component {
  constructor() {
    super();
    this.tick = this.tick.bind(this);
  }
