I remember arguing with Ron on the TC39 disposable proposal that I think Go's `defer` is a better pattern than C#'s `using`, and he tried to convince me the otherwise.<p>I was surprised to see they choose Go instead of C# for the TypeScript compiler port. Microsoft has been trying to make ECMAScript look more similar to C#, and their Windows Universal SDK has made a lot of efforts to provide a seamless transition for developers to port their code between C# and TypeScript. And yet they still think porting TypeScript compiler to Go is easier to do than porting it to C#.<p>Despite my different tech view with Ron, I appreciate and respect the great work he has done to TypeScript & ECMAScript. And I wish him the best with his next adventure.
