I will add a new full stack javascript Training catalog section. This will include:

• Getting started sections for Node.js and React.js
• Add SWAT talk presentation for React.js and Node.js
• Links to turtorials/learn more pages for Node and react
• (optionally) getting started with deploying it to heroku.

Background (Technical Details)

Node.js is an open-source, cross-platform JavaScript run-time environment for executing JavaScript code server-side. It has an event-driven architecture and operates on a single thread, using non-blocking I/O calls. Since all requests are single threaded, it requires that any function performing I/O must use a callback (using an observer pattern). These design choices aim to optimize throughput and scalability, allowing Node.js to support tens of thousands of concurrent connections without incurring the cost of thread context switching.

References:

• RxJS api
• ReactiveX - main website which explains what are observables/observers.
• RxMarbles - super cool website which visually explains all the observable operators/api functions.

$scope.$watch to rxjs.observer:

Angular $watch and rxjs observers are basically the same thing. They just have different semantics. This is why angular 2 will completely remove $watch and directly use rxjs.

// promise handles user not found by returning `null`
// advantage - don't have to write a reject handler
// disadvantage - requires developer to know the implementation detail of the facade function
//                that it returns `null` or not. Higher possibility of forgeting to write `null`
//                check and cause null pointer exception

    return facade.user.getUserByEmailAddress(emailAddress).chain(function (user) {
