ECMAScript 6 and Rest Parameter Mar 6, 2013 2 min read #es6 #javascript #web Handling a function with a variable number of arguments is always tricky in JavaScript. At least, we still have this arguments object which can be used to retrieve all arguments used to invoke a function. With the upcoming ECMAScript 6, no such hack is necessary anymore since we can start using its rest parameter feature.

es6-shim – ECMAScript 6 functionality on ECMAScript 5
Update 2012-03-13: Added a section on installation. Paul Miller’s es6-shim gives you functionality that will be in ECMAScript 6 (code-named ECMAScript.next), on ECMAScript 5 engines. It was initially based on a project of mine, but adds much new functionality, Node.js compatibility, and (not least) tests. Highlights The following are a few highlights.

This is an (almost) complete overview of the ES5 specification. ECMAScript is the language that governs JavaScript. Although meant to be finished some day, I'm just too busy right now. Most notes were a first draft. The meta javascript language is not using a very consistent api, etc. But seeing how others are popping up (see below), I guess I should publish my notes and see whether I'll take the

ECMAScript 5 is on its way. Rising from the ashes of ECMAScript 4, which got scaled way back and became ECMAScript 3.1, which was then re-named ECMAScript 5 (more details)- comes a new layer of functionality built on top of our lovable ECMAScript 3. Update: I’ve posted more details on ECMAScript 5 Strict Mode, JSON, and More. There are a few new APIs included in the specification but the most inte
