Here is a code translator for converting a python code to JS code. After getting so much used to python, it might be a bit difficult to go back to JS Code, but this python module can help us a bit once we get used to it I guess.
How to install ?
You can use pip to install this Py to JS translator
pip install pythonscripttranslator
How does this work?
Lets first create a small hello word python script
echo 'print "Héllo World"' > app.py
Once you have the script, you just need to do following
pythonscript < app.py > app.py.js
