pyjsparser

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. If you need full ECMA 6 support I recomment trying out this parser by Kronuz.

Installation

pip install pyjsparser

Example

>>> from pyjsparser import PyJsParser
>>> p = PyJsParser()
>>> p.parse('var $ = "Hello!"')
