Converts JavaScript to Python ES modules

Proof of concept, converting JS to Python in Pure JavaScript ES modules, for example:

import { BigNumber as BigN } from "https://unpkg.com/bignumber.js@latest/bignumber.mjs";

class MathDevice {}

class Calculator extends MathDevice {
  constructor(args = []) {
    super({})
  }
  static max(a, b) {
    return BigN.max(a, b)
  }
}

into

class MathDevice:
  pass

class Calculator(MathDevice):
  def __init__(self, args = []):
    super().__init__({})

  def add(self, a, b):
    return max(a, b)

BigN is a special name for bignumber.js

Usage

in JavaScript

import { JS2Py } from "https://code4fukui.github.io/js2py/src/JS2Py.js";

const f = new JS2Py()
const js = `for (let i = 0; i < 10; i++) { for (let j = 0; j < i; j++) { i + j }}`;
console.log(f.convert(js));

as a command

deno run -A cli.js example.js

Test

cd test
deno test JS2Py.spec.js
