fix argument name bug

This is nitpicky, but in your repl illustration you're using the word "cat" In the function name and the "kitty" in the constant name. "Cat" and "Kitty" are basically two words that mean the same thing, but what you're really trying to express is that the constant is a particular cat. "Kitty" doesn't really convey that so maybe the constant name should be "myFavoriteCat" or "myCat" or something like that??

function sayNameAndAge(cat) {
  return console.log(`My name is ${cat.name}. I am ${cat.age} years old.`)
}

const kitty = {
  "name": "Sylvia",
  "age": 6
}

// prints "My name is Sylvia. I am 6 years old."
sayNameAndAge(kitty)
