sounds like you have a good manager. you should take a moment and feel happy about that :)

I agree you should avoid inheritance, but it’s the fact that Scala supports inheritance that makes type inference difficult (also null). Type inference in Haskell is much better, for example. I saw a great presentation on the topic by Tho

I think mixing the OO and FP is the crux of the problem. Type inference and subtyping (class based inheritance) don't mix well, and often require type annotations to help the compiler when types get somewhat complex. Eventually you dev

I could remember everything about every codebase I had ever written up until about the age of ~30. Now at the age of ~40, I can't remember what I wrote two weeks ago. It'll happen to you ;)

I need to write a blog entry titled, "Your test suite is basically a sh*tty type system." -- I'm in the "totally anal" camp of type system aficionados :)

it drives me absolutely insane that this TypeScript compiles: const num: number = [][0]

I loved this book when I read it in college. Things people should know: * It's funny. * Benjy is just one of the characters. He has mental issues, which make his chapters more difficult, but the other characters' chapters are stra

Server Side Rendering is a good use case. If you want to pre-render a data visualization that can be loaded with a web page, you can use something like this in place of the browser's canvas, but use the same code to generate the data v

Pure functions with clearly defined type signatures are always preferable, in my opinion, because there is far less thinking involved. Elm's vdom is done in this way, as is the vdom used in PureScript Halogen. React is great, and groun

"becoming" - it has been since the beginning. You have to import the react library or it doesn't work. You create classes but never instantiate them. JSX is invalid JavaScript syntax. It's a veritable cornucopia of black

heh, I'd take tag out of there and let CI handle that. Good list though.

I've had engineers tap me on the shoulder with a proud look on their face while pointing at some crazy mess of branches they've just spent hours futzing with to finally get "right". It would have taken them a fraction of

Yeah I agree with @ff_57 here - the "breaking changes" really aren't a big deal, and don't effect many libraries. With the existing tool chain you will know immediately if a library has any of these incompatibilities, an

Once you get a taste for higher kinded types (aka: type constructors), there is no going back! PureScript is fantastic language with an active an open community. Best place to start (IMHO) is https://github.com/lumihq/p

Functional Programming provides a great solution to this problem. You learn what a Functor, Applicative Functor, and Monad are, and then the concepts remain useful for the rest of your life. Below is an amazing blog entry on how to apply fu
