Excerpt: Can time be part of a contract? Is it a contract when time is included? «Shall we meet at half past eight at the Pub for a beer?» Let’s steer past that one. Timing requirements are important, they are extensively used in hard real-time systems. In some protocols a client does not need to send any «end of request» signal as the server times out after a period of inactivity to close the connection (like HTTP persistent connections). This blog note tries to discuss when timeouts are fine to use, and when they do turn the components’ interactions into a quiz.
Excerpt: I hope it to be a note showing whether it’s possible to code the animated tree in concurrent JavaScript code.

Even Back-End developers are more likely to use it than any other language» – stackoverflow Developer Survey Results 2016. In other words: most of the world’s programmers are deprived of concurrency support in their programming language.
