> Even if I have been writing code with Java / C# for nearly a decade , nothing has come close to Typescript in terms of productivity,flexibility and confidence.

TypeScript is, by far, my favorite type system. I love structural typing. I love conditional types (ReturnType<T>). I love things like `keyof T`. I love how good it's inference system is. I love how I can still use it in a JS file and still get type checking with JSDoc.

I tried out Dart over the holidays and it felt like a major step backwards. Seriously, hats off to the developers.
