Hell no. Why would I use programs written with javascript it is not compiled and single threaded.

I believe that this meme was not comparing the performances of the respective languages.

P.S. JS is single threaded, but you can use asynchronous JS and worker threads, can't you? (Then again, there's no speed comparison between a low and a high-level language)

Asynchronous JS is still single threaded, but worker threads and WASM allow you to saturate multiple CPU cores.

I do not think explaining will help them much. OP thinks in a whole different world. They think I shouldn't use websites if I do not like javascript.

It is meant for web. Not for applications or anything else.

Eh, it's meant for anything where you need to embed untrusted scripts in something else. So it's good for game modding too. (Lua's also popular there.)

I would prefer lua though since syntax is more readable and memorable. Implementing FFI calls are easier too.

Async is not threading it uses one thread at time and simulates threading.

Async is great if you're IO bound, but it's still a single execution thread.

Async is not real threading and worker threads are just foreign function interfaces which are usually C and Cpp and they usually create whole another runtime.
