 [React](https://reactjs.org/) is a popular JavaScript library for building user interfaces (UI). React is a declarative way to create reusable components for your website.  There are many other popular libraries for JavaScript-based front-end development.  We'll use a few of these libraries while creating our lab.  [Redux](https://redux.js.org/) is a library that provides predictable state container for JavaScript apps and is often used in compliment with React. [JSX](https://reactjs.org/docs/introducing-jsx.html) is a library syntax extension to JavaScript often used with React to describe what the UI should look like.  [NodeJS](https://nodejs.org/) is a convenient way to run a webserver for your React application.

-Official Ubuntu builds have [iptables](https://help.ubuntu.com/community/IptablesHowTo) installed and will allow all incoming traffic by default.

 ## Cost
 
-Let’s cover an example cost estimate for this class.  Suppose you have a class of 25 students. Each student has 20 hours of scheduled class time.  Another 10 quota hours for homework or assignments outside of scheduled class time is given to each student.  The virtual machine size we chose was **Small**, which is 20 lab units.
+Let’s cover an example cost estimate for this class. The virtual machine size we chose was **Small**, which is 20 lab units.
