function barista(coffees){
const coff=coffees.sort(function(a, b){return a - b})
let time=0
for (let i=0; i<coff.length;i++) {
time+=coff[i]
for (let j=0; j<i;j++) {
console.log(coff[j])
time += coff[j]+2;
}
}
return time
}
barista([4,3,2])
I understood that coff[i]
gives me 2, 3 ,4
. But I don’t understand why coff[j]
gives me 2, 2, 3
. Where exactly did those numbers come from?
