I little bit confused with the starting value in this project

Hi folks, could you please help? Both the following codes work. I don't understand why the second one is good, because I can't imagine how the browser interpret this line: 'highest.price' if highest = 0 ?

The good one in teachers note:

const product = products
  .filter(product => product.price < 10)
  .reduce((highest, product) => {
    if (highest.price > product.price) {
      return highest;
    }
    return product;
  }, { price: 0 });

The bad one which also works:

 const maxcheep = products
  .filter(product => product.price < 10)
  .reduce((highest,product) => {
    if (highest.price > product.price) {  
      return highest;
    } else {

      return product;
    }

  },0);

see here above the acc value is 0 => means that highest = 0 => how can the browser read 0.price ?
