Question

What’s wrong with this JavaScript?

var numPackages == 0;

if (coffeeProducts <= 12) {
  numPackages == 1;
} else if (coffeeProducts % 12 == 0) {
  numPackages == coffeeProducts/12;
} else {
  numPackages == (coffeeProducts/12) + 1;
}

Basically, it needs to calculate the number of boxes/packages necessary to ship an amount of items (12 per box). Is there a better way to do this, perhaps using round()?

Answer 1

All the others explained your mistake with the comparing operator == and the assigning operator =.

The shortest way to solve it would be

var numPackages = Math.ceil( coffeeProducts / 12 );
