pythonlang's intention is to import all Python 3 Built-In Functions to Javascript, while keeping the performance hit to a minimum.
- Javascript is rife with facepalm inducing quirks and unexpected behaviors
- Python is fun; Its built-ins are reliable, simple and consistent
- Therefore, translating Python's built-ins into JS will reduce the amount of facepalms and make things better overall
- 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.
| 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 |
- Strict equality doesn't work yet, eg:
int(3) == 3 >>> true int(3) === 3 >>> false
- No bundling tools
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)
