I can't stand this JS is sooo fast bullshit anymore. You just suck at coding if your code with the most other languages is significantly slower.

True, haha. Yesterday, tried out electron it was so slow...

Well, I work with multiple languages and It is pretty fast... In my experience at least 😓

@linuxxx yeah, but if you compare that too c++ or c for example. It is much slower ofcourse.

@Jifuna Nope. In my experience it can even be faster sometimes (yes, I've worked with both)

@linuxxx oh, hmm didn't know that.

@Jifuna literally just ran a lot of benchmarks and compared (like create two things that do the same and compare the time)

@linuxxx okay, and what was the difference? I'm curious.

Ouch. Faster than the language the interpreter is written in?
Ahm ... Nop.

Nobody says JS can't be fast under certain circumstances.
But especially if you say something like C is slower u just don't use C to it's full extend and just made a benchmark which is nice to JS.

@Jifuna Can't recall much but it took JavaScript about 200ms and c++ like 400ms

It's not about being faster than C++ or something, but it's impressive how fast it is running for an interpreted language. Which begs the question - in which browser. Which is actually similar (but not the same as) how a different compiler makes a difference to your compiled code if there's multiple compilers for that language.
So yeah, a language doesn't necessarily have "speed", it's more about how the available compilers/interpreters run with the language possibly being a bottleneck if you can't split the language commands into smaller chunks of machine code.
