You useddisplayHogwartsNames function as a callback function for the forEach method. Being able to pass a function as an argumetn is one of the Java Script's fundamental concepts. Can you name this concept in JS?


function teachersWithPets({firstName, lastName, pet, occupation}){
if (occupation==="Teacher" &&pet){
console.log(`${firstName} ${lastName} has a ${pet}`);
}
}
hogwarts.forEach(teachersWithPets);

Well done for using object destructuring as a parameter!
However, the printed result doesn't quite match to the expected result.

  1. missing column names: It should print out the column fields: QTY, ITEM, TOTAL in order and correct values for each column.
  2. number formatting: 232 should be 2.32
  3. missing Total: total price is missing
    Please refactor the code to match the expected result in readme.md
