Accessing Object Properties with Variables

JavaScript
1

I am a little bit confused about this lesson: https://www.freecodecamp.org/learn/javascript-algorithms-and-data-structures/basic-javascript/accessing-object-properties-with-variables
what is the use of accessing the object property like this:

const dogs = {
  Fido: "Mutt",
  Hunter: "Doberman",
  Snoopie: "Beagle"
};

const myDog = "Hunter";
const myBreed = dogs[myDog];
console.log(myBreed);

when you can do this much easier by console.log(dogs.Hunter):

You don’t always know which property you will need to access when writing a more general function.

This way you don’t need to make a separate function for every single thing you want to do to every single possible property.
