What (in my opinion) one can learn from Erlang/OTP for other programming languages
12 mins
Since I'm a huge fan of the Erlang programming language and the OTP toolkit but normally aren't working with projects where Erlang is suited or in case some existing code is using already other languages and so I'm not capable of using Erlang I tried to summarize some of the things that I think one can learn from programming in Erlang/OTP even when using other programming languages. Of course this stuff is not enforced by the runtime environments and it's harder to achieve on other platforms but the approaches work nevertheless.
