Cant get "For In" loop to work for Create an Array of Objects

// 1. Create an array named products.
let products =[
  {
  name: "Blue Rubber Ducky",
  inventory: 2,
  unit_price:5.99
  },
  {
  name: "Red Rubber Ducky",
  inventory: 3,
  unit_price:4.99
  },
  {
  name: "Black Rubber Ducky",
  inventory: 4,
  unit_price:6.99
  },
  {
  name: "Purple Rubber Ducky",
  inventory: 5,
  unit_price: 2.97
  }

];

function listProducts(prods){
  let names =[];
  //for(item in prods){
  //  names.push(item.name);
  //}
  for(let i=0 ; i<prods.length ; i++){
   names.push(prods[i].name); 
  }
  return names;
}

console.log(listProducts(products));

Why can'tI get this for/in syntax to work?

SOLVED - Got it, was missing the reference to prods

function listProducts(prods){
  let names =[];
  for(item in prods){
    names.push(prods[item].name);
  }
  return names;
}

Come to think of it though, ANYONE know what the difference between a for/in and for/of loop is/are???
