Experimental support for WebAssembly in V8 · V8
Show navigation For a comprehensive overview of WebAssembly and a roadmap for future community collaboration, see A WebAssembly Milestone on the Mozilla Hacks blog. Since June 2015, collaborators from Google, Mozilla, Microsoft, Apple and the W3C WebAssembly Community Group have been hard at work designing, specifying, and implementing (1, 2, 3, 4) WebAssembly, a new runtime and compilation target
command line CoffeeScript
CoffeeScript seems to be picking up some momentum these days. No doubt, it is very valuable to help writing cleaner code. The command-line choices to run CoffeeScript compiler right now are either using Rhino (jcoffeescript) or using NodeJS. While I love NodeJS, seems that it is an overkill to require the entire NodeJS stack/infrastructure/package manager to invoke CoffeeScript compiler. The solut

John Resig - JavaScript in Chrome
Google Chrome has taken the browser world by storm. It makes for an exciting release, no doubt, especially with a brand new JavaScript engine on the table. However the most important question, to JavaScript developers, is: How will this affect my normal development routine? I’ve done some research, talked to some developers, submitted some bugs and come back with a list of things that you should p
John Resig - JavaScript Performance Rundown
A new JavaScript Engine has hit the pavement running: The new V8 engine (powering the brand-new Google Chrome browser). There are now a ton of JavaScript engines on the market (even when you only look at the ones being actively used in browsers): JavaScriptCore: The engine that powers Safari/WebKit (up until Safari 3.1). SquirrelFish: The engine used by Safari 4.0. Note: The latest WebKit nightly
