What does React do?

	//-------------------------------Main (parent) component
	var Main = React.createClass({
	// props: name (data)
	// state: counter (data)

	getInitialState: function() {
	return { counter: 0 };
	},
	handleClick: function() {
	this.setState({ counter: ++this.state.counter });

	// Write a recursive function that outputs the range between two positive numbers
	// myFunction(1, 5) #=> [1, 2, 3, 4, 5]
	// (5 pts)


	// Write a recursive function that outputs the sum of an array of integers
	// myFunction([1, 2, 3, 4, 5, 6]) #=> 21
	// (5 pts)

	///// index.js

	import React from 'react';
	import ReactDOM from 'react-dom';
	import HelloWorld from './HelloWorld';

	ReactDOM.render(<HelloWorld name='Meeka' />, document.getElementById('container'));


	///// HelloWorld.js

	/// Older
	///////////// Here, we specify the defaultProps and the initialState in functions in the component
	///////////// We also validate the component props in the propTypes function

	var Counter = React.createClass({
	getDefaultProps: function(){
	return {initialCount: 0};
	},
	getInitialState: function() {
	return {count: this.props.initialCount}
