I come from Python/JavaScript so I really don’t have any idea about how should I make code run faster besides writing less.
I really get confused when I hear YouTuber saying something like “C compiled 3 run faster than C compiled 1” (or something like that)
Now I started to get into my first static language, , I got introduced to a few things that can make my code run faster than my normal Python as using uint8 instead of uint when I’m declaring a human age for example (as age will be <0 <120)
But I can assume that there are many many other things that could make my Go code run much faster, or even as fast as Java or C++ as some here say.
I would really appreciate if someone could just list them out and I will spend my time googling for them, thanks so much

I don’t think I should ask in the same question but… can run faster than the very fast languages like C++ or Java or it can only run faster than Python/ JS/ Ruby, etc…
