Towards ECMAScript 6 with Esprima 2 Feb 9, 2015 3 min read #es6 #esprima #javascript Little did I know that the start of my adventure with Esprima three years ago will result in something beyond my expectation. While the syntax tree format used by Esprima is not original (see SpiderMonkey Parser API), this de-facto format gains a lot of traction since it provokes a Cambrian explosion of composable
Esprima 2.0 Released | Official jQuery Blog
Last week, the jQuery Foundation announced our adoption of the Esprima project, the widely used JavaScript parser that powers many code analysis tools. Today we’re pleased to announce the release of version 2.0, now available on npm. Up until now, the official releases of Esprima have only parsed ECMAScript 5 standard syntax. However, the experimental “harmony” branch has been adding ECMAScript 20

jQuery Foundation adopts Esprima | Official jQuery Blog
The jQuery Foundation is excited to announce that we are now hosting the Esprima project! The Abstract Syntax Tree generated by this JavaScript parser is used by many important developer tools such as ESLint, Istanbul, JSDoc and JSCS. Ariya Hidayat has decided to transfer ownership of the Esprima project and its repo to the jQuery Foundation. We’re glad that Ariya has taken this step, since Esprim
GitHub - Rich-Harris/magic-string: Manipulate strings like a wizard
Suppose you have some source code. You want to make some light modifications to it - replacing a few characters here and there, wrapping it with a header and footer, etc - and ideally you'd like to generate a source map at the end of it. You've thought about using something like recast (which allows you to generate an AST from some JavaScript, manipulate it, and reprint it with a sourcemap without

Getting Started with Esprima | The Jackal of Javascript
Thanks to two awesome people (Nick and Andy), for introducing me to Esprima. If you have never heard about Esprima, here is a quick intro. Esprima is a high performance, standard-compliant ECMAScript parser written in ECMAScript In simple words, Esprima is a Javascript parser.

2014-12-30のJS: jsdom 2.0.0、6to5 2.0.0、HTMLBars
JSer.info #208 - DOMのJavaScript実装(Node.jsでも動くDOMの実装)であるjsdom 2.0.0がリリースされました。 機能的な追加ではないですが、2.0.0となったのは今までDOM Level{1,2,3}別で実装されていたが、今後はLiving Standardモデルで実装していくという方針を示すためだそうです。 バージョン番号をつけるのはメリットよりもデメリットのほうが多いという過去の経験やjsdom内部でもlevel別だと辛い感じになってきたので、Living Standardモデルへと変えていくことになったようです。 公開APIについては殆ど変更はありませんが、内部的にかなり構造を変更していくリファクタリングをして行くようです。 ES6のコードをES5へ変換するツールである6to5 2.0.0(現時点で2.2.0まで出ていますが)がリリースされ
