pythonlang

Description

pythonlang's intention is to import all Python 3 Built-In Functions to Javascript, while keeping the performance hit to a minimum.

Motivation

1. Javascript is rife with facepalm inducing quirks and unexpected behaviors
2. Python is fun; Its built-ins are reliable, simple and consistent
3. Therefore, translating Python's built-ins into JS will reduce the amount of facepalms and make things better overall

Rigorousness

• A given built-in is considered complete only if all of its tests from CPython source are translated to JS and passing.
• The implementation in JS is kept as similar as possible to the source implementation of Python in C.

Progress (July 26 2019)

Built-in	Tests written	% Tests passing	Status
int	603	100%	Stable ✅
bool	5	60%	Lacking features, stable
abs	8	100%	Lacking features, stable
any	1	100%	Lacking features, stable

... > 60 untouched

Known Issues

• Strict equality doesn't work yet, eg:

  int(3) == 3
  >>> true
   
  int(3) === 3
  >>> false

• No bundling tools

FAQ

Q: Are you really going to implement all 69 built-ins?
A: Probably not. Some of them can't be implemented anyway (like classmethod), and some of them are rarely used and are too complex to justify including them (like memoryview)
