Why "negative if" number don't counting in right way?

Question

When
let adults=-1;
let children=2;
let price = adults*12 + children*6;

if(adults < 0) {
adults = 0;
}
if(children < 0) {
children = 0;
}
console.log(price);

The console show me — 0
But
if adults is negative it's equal 0, then price=0*12+2*6=12
So, console need to show — 12

What's wrong?

Answer 1

Your price variable is calculated only once, at the beginning.
Even if you change the other variables (adults and children) later in the program, those will not affect the calculation any more.

Move the "let price" line after your if conditions.
