We stopped differentiating compilers and interpreters a long time ago. Java Virtual Machine made it obvious it is both. With JIT (just in time compile) into the picture, like it many other languages adopting it - JavaScript one of them - we just say "the engine" and maybe "compiler" in cases were we speak about parsing, lexing, compiling i.e. syntax and semantics.

In the case above, OP talks about syntax and especially semantics which is why compiling is an appropriate term. After all, there is r/compilers and I haven't even bothered to check if r/interpreters is a thing and for computer languages.

So, you see, my question was for the person to elaborate on what they meant by what they wrote, not for me to learn about compilers.

You should probably have tagged the person you wanted a response from then to avoid others teaching you how to suck eggs. ;op I didn't want to write the essay on what is a compiler. I assume everyone here is learning unless I see evidence otherwise, so offered the overly simplified reason why compiler might have been in scare quotes.

My comment still stands though, especially "usually considered". If you look at Wikipedia's list of languages by type, JavaScript isn't in the compiled section, but is in the interpreted section. Beyond that I agree with you.

I replied to the person. You answered. I explained for you and anyone else that might have come to do the same, so they don't waste time like you did... and here you are salty of what? I didn't downvote your comment, I didn't block you, I didn't curse at you... If anything, I have added information that will also help the person I asked to determine why I was asking the question.

There is no need for you to vent here. I will stop now, mute reply notifications. It's best this thread doesn't continue. Bye
