Believe it or not, there are still a large number of .NET developers these days, that are happy to stay in the server domain, writing code only in C#
While that may be your thing (and I'm not going to stop you) .... you owe it to yourself to at least explore the world of front end code.
Fear not however. There is a way you can explore programming in the browser, and still maintain all this nice stuff your used to in C# code, things like Type safety, OOP programming and generics.
That Way is called TYPESCRIPT
You'll get to play in the browser, while still thinking and working in a very back-end programmer like way.
I'll not be teaching you the Typescript Language, nor will I be showing you any majorly cool coding tricks, I'll simply just be showing you that coming out of the server room, doesn't have to be painful at all.
