People always say this but its not technically correct and can be misleading.
Technically, JavaScript runs single threaded but not Node.js itself and certainly not when using it on the backend in something like Express. IO operations and other things tooling libraries do can cause you to run out of a thread pool. But Node.js, when handling requests, gives you much of the benefit of multithreading without having to deal with multithreaded code.
Aaaahh so libuv actually runs a thread pool, TIL. I'm another victim of internet propaganda I guess ๐ . You know, I never actually checked libuv docs until now and they seem quite welt built.
The silliest thing I've just realized is that I knew that the first implementation of a web server in dotnet core was using libuv, and I still didn't think twice about the single threaded meme.
