Build Status

Fast JavaScript parser - manual translation of esprima.js to python. Takes 1 second to parse whole angular.js library so parsing speed is about 100k characters per second which makes it the fastest and most comprehensible JavaScript parser for python out there.

Supports whole ECMAScript 5.1 and parts of ECMAScript 6. The documentation for the generated AST can be found here.

Installation

pip install pyjsparser
