It was designed to be fast and comprehensible, translating esprima's logic directly to Python rather than wrapping a JavaScript engine.\n\nThe parser handles ECMAScript 5.1 fully and supports parts of ECMAScript 6. It produces AST output compatible with esprima's format, making it useful for static analysis, code transformation, or tooling that needs to understand JavaScript structure without executing it. However, the package has not been maintained since 2019, so it will not evolve with newer JavaScript standards or receive compatibility updates for recent Python versions.","worth_installing":"Yes, if you need to parse ECMAScript 5.1 code and can accept an unmaintained package. The parser has no dependencies, installs easily, and carries no known vulnerabilities. However, avoid it for modern JavaScript projects that rely on ES6+ features, and be aware that bugs or Python compatibility issues will not be fixed. Consider whether a maintained alternative better suits your timeline."},"id":"pyjsparser","links":{"html":"https://skillfed.io/packages/pyjsparser","md":"https://skillfed.io/packages/pyjsparser.md","pypi":"https://pypi.org/project/pyjsparser/"},"maintenance":{"status":"abandoned"},"meta":{"latest_release":"2019-04-21","license_spdx":null,"license_treatment":"permissive","name":"pyjsparser","python_support":"unspecified","summary":"Fast javascript parser (based on esprima.js)"},"popularity":{"monthly_downloads":694728,"position":5313,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"2.7.1"}
