A startup team I am advising is going to program in Scala, Python, DJango and Web (HTML, CSS, Javascript, Jquery, Angular).
I see that there are three Intellij products - Intellij Idea (Scala), PyCharm ( Python and Django), and Webstorm (Web tech)?
Do we need to buy and use three different editors or can just one suffice?
If we use one, which one do we use and what do we lose compared to functionality of all three?
