What is the best language to develop a web front-end to access the Digi Cloud?

Hi,

I would like to develop a web front-end for my application and a lot of it is accessing the Device Cloud API.

I was thinking maybe Python with Django in a Heroku environment but have been reading that Python is best for the back end and Javascript with Node and Angular is better for the front-end.

Thanks in advance!

Either HTML or JAVA. Python is really not intend to be a Web app.
