is it possible to write a whole method that returns a value in ternary operator?

Question

Is it possible to do this kind of code in the ternary operator in javascript? If yes, I think I'm doing it wrong, when I tried the code below I wrote it just return the whole function(){} method

let products = [
  {
    price: 2.6,
    quantity: 5,
  },
  {
    price: 5.9,
    quantity: 5,
  },
  {
    price: 2.3,
    quantity: 5,
  },
  {
    price: 4.9,
    quantity: 5,
  }
];

let sumtotal = products.length > 1 ? function(){
  let total = 0;
  for(const { price, quantity } of products) {
    total += (price * quantity);
  }
  return parseFloat(total).toFixed(2);
} : function() {
  let total = (products[0].price * products.quantity);
  return parseFloat (total).toFixed(2);
};

console.log(sumtotal);

I was hoping that this would return an actual value like the output would be an Integer or float.
