GitHub - engine262/engine262: An implementation of ECMA-262 in JavaScript
While helping develop new features for JavaScript, I've found that one of the most useful methods of finding what works and what doesn't is being able to actually run code using the new feature. Babel is fantastic for this, but sometimes features just can't be nicely represented with it. Similarly, implementing a feature in one of the engines is a large undertaking, involving long compile times an

Editorial: disambiguate `with` statement's status by ddbeck · Pull Request #2441 · tc39/ecma262
Currently, the spec sends mixed signals to programmers about the with statement; this PR attempts to clear up the ambiguity by adding text that explicitly discourages the use of the with statement in new ECMAScript code. This is an attempt to solve a specific problem: developers and technical writers are unclear about the status of the with statement. See this StackOverflow question or this discus

C# 6.0がECMAでの標準化プロセス開始
The C# standards committee moved its work into Open Source, enabling C# developers worldwide to participate in the standardization effort. 情報源: Announcing Open Source C# standardization | .NET Blog 現状のECMA, ISO/IECのC#標準はC# 5.0ベースですが、「やっと」C# 6.0での標準化プロセスが始まるようです。まぁでも、国際標準化とはそう言うもので、逆に現行のC#仕様はC++でのBoostのようなものと言えるかもしれません。 ISO/IECの標準化など関係ないと考える人も多いとは思いますが、国際的な公共事業の入札案件などでは、開発言語、ランタイム環境がISO/IECへの準拠を求めら
