Unshackling JavaScript with MacrosMy JSConf 2014 talk (not so useful without speaker notes. video coming soon)

I’ve been pondering for a long time how to explain it well and I think the best way to do so is via four layers: single objects, prototype chains, constructors, constructor inheritance.

power-assertができるまで
power-assert を作るきっかけ アサーション失敗時の情報量を大幅に増やすことができるPower Assertの系譜 - Togetterまとめ chai/should/expect.js 覚えること多くて煩わしい 自分で作ろうと思い立った(2013/01/08) AST 変換 power-assert は最初から AST 変換で実現しようと考えていた Groovy の Power Assert が AST 変換を行っているらしいことは何となく知っていた Groovy 1.7 Power Assert パワーアサート(Power Assert)の真の意味 Groovy 1.7のキモはAST変換である 実装を見てはいないので、 Groovy の Power Assert が最近 AST 変換を行っていないらしいことは知らなかった…!
TypeScript用フルスタック型付きライブラリのご提案 #葉桜JS
https://github.com/teppeis/closure-ts We need KATA! 異論は認めない。 There are many Typed-AltJS. M社 G社 D社 H Typed-AltJS requires a typed library. 静的型付け指向ではないライブラリに型定義を与えて使っても型の力は活かせない（古くてごめん） Closure Library! 現存する唯一のフルスタック静的型付けJSライブラリ（当社調べ） closure-ts: Use Closure Library in TypeScript Closure LibraryのJSDocとコードをDoctrineとEsprimaでパースしてTypeScript用の型定義ファイル(d.ts)を吐き出す。 まだ昨日数時間実装しただけのPoCレベル いくつかのファイルは生成に成功 オリジナ
