The operating system can schedule multiple threads at the same time, but the language and runtime decide how application work reaches those threads. That distinction explains why Go, Rust, C++, Java, JavaScript, and PHP can all use a multicore machine even though their programming models look very different.</p> <p>The useful question is not simply whether a language is &ldquo;multithreaded.&rdquo; It is how a unit of application work becomes something the operating system can schedule.</p>
