      @skeuomorf @tqbf @aredridel psst, JavaScript is single-threaded and can’t do parallel operations. You mean “concurrency”

      @bascule @skeuomorf @tqbf pedant. Also incorrect in this case on a technicality.

      @aredridel @tqbf it’s an important distinction, IMO. @skeuomorf thought so too at least 😉

      @aredridel @tqbf as @skeuomorf pointed out, @rob_pike has an entire talk dedicated to the subject: https://www.youtube.com/watch?v=cN_DpYBzKso …

          @bascule yeah, though if you actually look at what is going on, it is parallel, implemented with a thread pool.

          @aredridel curious where Gulp keeps its thread pool… all I found was this: https://github.com/gulpjs/gulp/issues/317 …

          @bascule not gulp. Node.

          @aredridel Node’s use of threads is limited to exposing blocking system calls to single-threaded asynchronous upside-down world

          @bascule yes. Which makes it a really interesting thing in terms of parallelism and concurrency. It's the boundary there.

          @aredridel it’s taking facilities the kernel exposes for parallel multi-threaded use and limiting you to a single-threaded API

          @aredridel tl;dr: Node programs are single-threaded even if some facilities use a thread pool

          @bascule and the whole notion of IO is parallel, using distributed device(s) and doing things at the same time.

          @aredridel the kernel is fulfilling requests in parallel, but the orchestration is purely sequential…
