<p><pre><code>    in case of high level platforms, languages or libraries     
    it can be claimed that Erlang virtual machine is almost 
    unique because JVM threads depend on operating system 
    schedulers, CAF which is a C++ actor library uses 
    cooperative scheduling, Golang is not fully preemptive 
    and it also applies to Python’s Twisted, Ruby’s Event 
    Machine and Nodejs.

Most languages&#x2F;runtimes that are taking concurrency seriously do so using libraries or frameworks (eg Akka on the JVM) that look a lot like Erlang&#x27;s under the hood. Erlang is not quite as unique as it was, but obviously baking it into the language is v useful.
