We have three approved languages - C#, JavaScript and Python.

Of course C# you get all of the advantages of statically typed languages, so for major programs where you wil have multiple developers, it’s the go to language. But for smaller scripts like event based lambdas and scripting type scenarios, C# is overkill. Besides, each piece of AWS functionality is in its own NuGet package as opposed to one package for everything for JavaScript (Node) and Python.

JavaScript - our product is web based. Every developer is expected to know JS. So if someone decides to do a simple Microservice or lambda in C# or JS, it’s okay. Whichever they feel like doing, it’s okay.

We have another team that does a lot of ETL type processing. I doubt that many people would argue that JS is a better language for it than Python. If you are on that team and need to write something, you can choose whichever of the three languages you wish.
