So I am a Python dev. I originally wrote the back end for our application in Python. After a few months the decision was made to switch it to nodeJS, why? To this day I am not really sure. So the higher ups got someone in to convert my code to node. From around Christmas last year I had to learn node, add features and maintain someone else code base. Then about a month ago we hired a senior python dev, to his shock there is no py in our code all.
