maybe its just what your used to. Most of my time I code in Java (and a bit of Scala) and i only look at the source code as a last resort. This is not really possible with JS. But i imagine with a lot of background in dynamic languages you instinctively look at the source-code and therefore not use the types that much.

I looked at SO much Java sources because the method signatures weren't complete enough. I would never have been able to integrate netty into our game servers that optimally with only the docs as reference for one. Yet its documentation is really, really good. I still wanted to know its internals in order to hit the fast paths. Whether you're using static or dynamic types, the very same holds true to build robust software: understand what you're doing. Managing complexity and reducing state will always be the biggest factors to quality, regardless or type systems.

  Well, considering the number of dependencies a typical web project has, I can tell that I'm far from understanding the internals of every library used in our codebase. I mean, of course you'll want to do that in some cases where performance is really important, but generally speaking type signatures and docs should be enough.

  i din't say that i don't look at source code, but not intuitively. I look at it when the method is very confusing, or i have to optimise one path, it is undocumented and important etc. What i wanted to say is that types give you a pretty good first intuition to what the method does and how (including exceptions). They help me navigate my way through the code, especially with DSL like the excellent jooq (http://www.jooq.org http://www.jooq.org)

...And I hate java (for perverting OO, and being annoyongly verbose), and come from a highly dynamic background. It's ultimately a matter of preference, though.

  not that java is my favourite language, i would even say that i despise it. But its here to stay and the discussion was about shitty static type-systems where Java is the poster-boy ;)

    It's not even the shitty type system: C's is arguably even worse. No, it's the fact that it's effectively the new COBOL.

Java: the language so ugly it has to wear a (IDE plugin) bag over its face while you're doing it. Yes, I'll go have that talk with H/R now...
