I think you are confusing async and sync. Nowadays, both sync (serial) and async (parallel) operations can happen on a PC, as every single core in the CPU can work in parallel with the others. Normally node runs on a single process (and core) so it's not multithreaded (unless you use some specific modules), and simulates preemptive multitasking like the OS scheduler do. Async operations in node are necessary to avoid blocking the "core" (the whole app) while waiting, for example, for a file to be read or a socket to receive data. > Some operations > need to wait for something else to finish. These are async operations. No. those are sync operations. > In some environments, async operations are made to look synchronous > using things such as threads, processes and fibers.
