Our goal is not to build a platform; it’s to be cross all of them. — Mark Zuckerberg CSCS (Customized Scripting in C#) is an open-source scripting language implemented in C#. Syntactically it’s very similar to JavaScript, but it also has some similarities with Python. Some of these similarities are the keywords in the well-known if…elif…else construct, and also have the same variable scope definition as in Python (e.g. a variable defined inside of an if block or inside a loop will be also visible outside).
