So - You Think You Know JavaScript?

This is a talk that I first gave at SkillsMatter in London in April 2011.

It's about 90 minutes; the first section covers the history and evolution of JavaScript, from Alonzo Church's work on the lambda calculus in 1936 right up to NodeJS and the Google Chrome Web Store. It then covers some of JavaScript's more esoteric language features, and finishes up with a couple of demos covering declarative binding using Knockout, client-side templated JSON using Tempo, server-side event-driven JavaScript using node.JS and a quick look at running HTML5 applications locally on iOS devices using an HTML manifest file.

If you'd like me to deliver this talk or some variation on it at your event or user group, please get in touch - I'm @dylanbeattie on Twitter or

You can use the code for whatever you like. You can download the slides to review and share, but you may not use these slides as part of a public presentation without my permission. A great deal of work goes into a talk like this, and the slide deck is only a part of it. If you want to use them in your own material, please contact me and I'm sure we can work something out.

Oh, and Eric Cartman's likeness is used without permission. Please don't sue me, Matt and Trey. I love you guys.
