The following is a VERY rough draft of an article I am working on for Alex MacCaw's @maccman's Book. It is very rough, but even now a worthwhile read. Suggestions / comments are very welcome! Please help me :-)

Introduction

JavaScriptMVC (JMVC) is an open-source jQuery-based JavaScript framework. It is nearly a comprehensive (holistic) front-end development framework, packaging utilities for testing, dependency management, documentation, and a host of useful jQuery plugins.

Yet every part of JavaScriptMVC can be used without every other part, making the library lightweight. Its Class, Model, View, and Controller combined are only 7k minified and compressed, yet even they can be used independently. JavaScriptMVC's independence lets you start small and scale to meet the challenges of the most complex applications on the web.

This chapter covers only JavaScriptMVC's $.Class, $.Model, $.View, and $.Controller. The following describes each component:

ETags: a pretty sweet feature of HTTP 1.1

HTTP caching review

HTTP provides two ways for servers to control client-side caching of page components:

freshness may be based on a date or a token whose meaning is app-specific
whether or not the client needs to confirm the cached version is up-to-date with the server

This breaks down as follows:

Cache locally and don't check before using.

This is a proof-of-concept of a couple of concurrent data structures written in Ruby.

The implementations are heavily commented for those interested. There are benchmarks (with results) included below. The results are interesting, but, as always, take with a grain of salt.

Data structures

AtomicLinkedQueue is a lock-free queue, built on atomic CAS operations.

Make it real

Ideas are cheap. Make a prototype, sketch a CLI session, draw a wireframe. Discuss around concrete examples, not hand-waving abstractions. Don't say you did something, provide a URL that proves it.

Ship it

Nothing is real until it's being used by a real user. This doesn't mean you make a prototype in the morning and blog about it in the evening. It means you find one person you believe your product will help and try to get them to use it.

Do it with style

Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.

ANNOUNCEMENT

I have moved this over to the Tech Interview Cheat Sheet Repo and has been expanded and even has code challenges you can run and practice against!

The introduction to Reactive Programming you've been missing

This tutorial as a series of videos

If you prefer to watch video tutorials with live-coding, then check out this series I recorded with the same contents as in this article: Egghead.io - Introduction to Reactive Programming.
