It's weird / funny to me how comfortable I've gotten in TypeScript, to the point that I prefer it over Java consistently. Not an outcome I would have predicted, but Microsoft does have a knack for building and maintaining good languages.

It's the hundred little things, like the fact that TypeScript constructors are (a) named "constructor" (one fewer thing to change in a refactor that renames the class) and (b) have a syntactic shortcut for passing in arguments that do nothing but get retained in the object state. Every time I write Java and I have to pass in a Foo named 'f' so I can write 'foo=f' in the constructor body, I die a little inside.
