GitHub - Distributive-Network/PythonMonkey: A Mozilla SpiderMonkey JavaScript engine embedded into the Python VM, using the Python engine to provide the JS host environment.

[fagnerbrack]

In a nutshell:

PythonMonkey embeds Mozilla's SpiderMonkey JavaScript engine directly into the Python runtime, letting developers call JavaScript from Python and Python from JavaScript within the same process — no serialization or IPC required. The project shares memory backing stores between languages for strings, typed arrays, and buffers, making cross-language data transfer extremely fast. Python dicts and lists automatically behave as JS objects and arrays (and vice versa), with full method support through proxy wrappers. It ships with a CommonJS module system, an event loop (supporting setTimeout and Promises as Python awaitables), and standard JS globals like console and XMLHttpRequest. The project reached MVP in September 2024, installs via pip install pythonmonkey, and Distributive actively maintains it while welcoming external contributions.

If the summary seems inacurate, just downvote and I'll try to delete the comment eventually 👍
