JavaScript Modify Object Properties

calling function processSale

how is it possible that the javascript engine recognises name: the element will be shown if we set the arguments

processSale(product, 5) - why it didnt call something else in the object instead?

addInventory(product, 3) - same thing here

how it can recognise we want name property to be called.

Thanks for reply

The code uses membership notation to access the name when creating the log message:

  console.log(quantity + " " + prod.name + "s sold");
//                             ^^^^^^^^^

The prod.name accesses the name property of the product. The addInventory function has nearly the same line of code and works the same way.
