We’re talking here about functions and not methods. For the purposes of this discussion

HexGL, the HTML5 futuristic racing game.
What is this? HexGL is a futuristic, fast-paced racing game built by Thibaut Despoulain using HTML5, Javascript and WebGL and a tribute to the original Wipeout and F-Zero series. Credits. HexGL was built with love using three.js, a 3D library built on top of WebGL and maintained by Mr.doob and AlteredQualia. I'd also like to thank Nobiax for the great metalic road texture, Charnel for the HexMKI b

It describes how proxies can be used to intercept operations on objects, allowing properties to be returned dynamically or exceptions thrown. It also covers other new features like maps, destructuring, arrow functions, and let/const that address issues with older variable scoping and

The Birth & Death of JavaScript
This science fiction / comedy / completely serious talk traces the history of JavaScript, and programming in general, from 1995 until 2035. It's not pro- or anti-JavaScript; the language's flaws are discussed frankly, but its ultimate impact on the industry is tremendously positive. For Gary's more serious (and less futuristic) thoughts on programming, try some Destroy All Software screencasts. If
