Install Firefox Nightly in Ubuntu via PPA

via: http://www.webupd8.org/2011/05/install-firefox-nightly-from-ubuntu-ppa.html

Add the Mozilla Daily PPA (available for Ubuntu 11.04, 10.10 and 10.04) and install Firefox Nightly using the commands below:

$ [sudo] add-apt-repository ppa:ubuntu-mozilla-daily/ppa
$ [sudo] apt-get update
$ [sudo] apt-get install firefox-trunk

Since this is a daily builds PPA, it's nowhere near stable so use it at your own risk!

React Hello World Examples

React "Hello World" Examples

Below are a small collection of React examples to get anyone started using React. They progress from simpler to more complex/full featured.

They will hopefully get you over the initial learning curve of the hard parts of React (JSX, props vs. state, lifecycle events, etc).

Usage

You will want to create an index.html file and copy/paste the contents of 1-base.html and then create a scripts.js file and copy/paste the contents of one of the examples into it.
