Exploring the Features of C# 11: The Modern Capabilities of a Vibrant Language [Webinar]
C# has evolved long since its introduction about 20 years ago. In this live-coding presentation, learn about the fascinating features of the most recent version of the language. We will explore the most interesting features, their power, and how we can benefit from them to create concise, expressive, and maintainable code. 

TypeScript lets you write JavaScript the way you really want to.

TypeScript is a typed superset of JavaScript that compiles to plain JavaScript.

Any browser. Any host. Any OS. Open Source. 

I can tell at least that in 3 years, JavaScript will gain more the status of a VM and lose the status of a language. Already today, not many people use raw JavaScript. You usually have some transpilation, at least e.g. Babel. In the future, Web Assembly will enable more innovation in that regards, and existing transpiling languages like Elm, TypeScript, PureScript will continue to improve.
