A Javascript stacktrace in any browser
This is now a mature project on GitHub! Please submit comments/issues there. Chances are that if you’ve done any significant Javascript work, you’ve run into a situation where part of the debugging process could be much improved if you just had the function call stack. I’m going to give you some ways of doing this with and without the popular Firebug extension and have some examples of their uses.

Creating your own JavaScript Library – MikeDoesWeb
One of the phases I went through while learning about JavaScript was the intense desire to write my own library, similar to jQuery (but massively scaled down). My library has gone through several major revisions — and more than one complete re-write, but now is exactly what I started out hoping it would be: functional, clean, small, and a solid learning experience. I’d like to share what I learned

harmony:typeof_null [ES Wiki]
under the Harmony version, but the Result would remain “object” under the default version. Version details TBD. Some JS on the web carefully tests both typeof x === “object” && x === null or equivalent in order to distinguish null from an object reference. Other code is less careful. The ongoing burden on JS authors, maintainers, teachers, and learners is a small but (over time) significant cost.
最近のJavaScriptモジュールの書き方 - yo_waka's blog
サーバサイド（特にNode.js）とクライアントサイド両方で動かしたいものは最近はこんな感じで書いている。 CommonJSのwiki見ててそこに紹介されてるソースコードで（どれだったか忘れたけど。。）やってたのを見ていいなーと思って真似っこした。 (function(define) { define([], function() { 'use strict'; /** * @constructor */ var SomeClass = function() { // initialize }; /** * @type {string} * @private */ SomeClass.prototype.hoge_ = 'hoge'; /** * @return {string} */ SomeClass.prototype.getHoge = function() { return th
John Resig - JavaScript as a First Language
At Khan Academy we’ve been investigating teaching Computer Science to students in some new and interesting ways. The most interesting aspect of which is that we’re likely going to be teaching them JavaScript as their first language. We’re in a very unique position as we’re primarily aiming to teach students who’ve been through our previous math and science-centric curriculum. Because of this we ca
Virtual machine and javascript engine
The document discusses virtual machines and JavaScript engines. It provides a brief history of virtual machines from the 1970s to today. It then explains how virtual machines work, including the key components of a parser, intermediate representation, interpreter, garbage collection, and optimization techniques.

19.12. Test Driven JavaScript Development – Mayflower Blog
A couple of weeks ago, I was attending a three-day workshop for agile developer skills. The workshop was split into five topics: Colaboration, Refactoring, Design & Architecture, Continious Integration and Test Driven Development. Especially the session about Test Driven Development was very interesting. Although I know the principles of TDD I was really impressed by the demonstration of solving a
JavaScriptの無名関数の実行 (function(){})() と (function(){}()) の違い | 圧縮電子精神音楽浮遊構造体
2011年12月17日土曜日 JavaScriptの無名関数の実行 (function(){})() と (function(){}()) の違い JavaScript Advent Calendar 2011 (オレ標準コース) 17 日目、polygon_planet です。 ずっと Advent Calendar 参加してみたいなぁと思ってたんですが ネタが思いつかない日々で半分諦めてたんですが、考え過ぎな気がしてきたので 別におもしろい記事でもないし、技術的にも参考になるのか不明ですがとりあえず書きます。 もしかしたら同じようなこと解説してる記事がすでにあるかも…(うまく検索できてない) JavaScript で無名関数をその場で実行するとき、 (function() { // 処理 })(); という書き方が主流っぽいですが、 (function() { // 処理
console.logのエイリアス - hokaccha memo
