That moment when you realise f(x)=x²
that you did in 4th grade and now
Function(x){
return x*x;
}
....😯😮😲😱😵...
You realise that Everyone has been doing programming all their life....

Programming basically is solving Math problems

4th grade?

Noiiiceeeee dude lol. Mindblowing right.😲😲😲😲

I think it's the other way around 😅

Computer science is a subdivision of math. You are still doing math just don't see it... ;)

Yeah, mathematics and computing are related, but what's up with that function? I can't image a situation where declaring a function for that would be useful. At least go a little more generic:
function pow(x,y) {
var z = x;
while (y > 1) {
z *= x;
y--;
}
return z;
}

(Yep, this only does positive powers, still)

Or just use Math.pow(). (That's js but all languages have math libraries)
