Javascript :: Arrays III : Spreading #js

ArraysIii:Spreading1.js

// Takes a formatted multidimensional array and outputs sentences using constants:
function zooInventory(aZoo) {
  let animalFacts = [];
  for (let i=0; i < aZoo.length; i++) {
    const currentAnimal = aZoo[i];
    
    const animalName = currentAnimal[0];
    const animalType = currentAnimal[1][0];
    const animalAge = currentAnimal[1][1];
    
    animalFacts.push(`${animalName} the ${animalType} is ${animalAge}.`);
    }
    return animalFacts;
}

// the same thing but refactored to use array spreading:
function zooInventory(aZoo) {
  let animalFacts = [];
  for (let i=0; i < aZoo.length; i++) {
    const [animalName, [animalType, animalAge]] = aZoo[i];
    
    animalFacts.push(`${animalName} the ${animalType} is ${animalAge}.`);
    }
    return animalFacts;
}

//when given this as a starting point:
let myZoo = [
  ['King Kong', ['gorilla', 42]],
  ['Nemo', ['fish', 5]],
  ['Punxsutawney Phil', ['groundhog', 11]]
];
