Tell us what’s happening:

what is the key differentiation of using animal[‘habitat’] and animal.habitat ?

Your code so far

const tiger = {
  species: "Tiger",
  age: 5,
  isEndangered: true
};

const elephant = {
  species: "Elephant",
  age: 10,
  isEndangered: true
};

const getSpecies = (animal) => {
  return animal.species;
};

console.log(getSpecies(tiger));

const getAge = (animal) => {
  return animal.age;
};

console.log(getAge(tiger));

// User Editable Region
const addHabitat = (animal, habitat) => {
  animal['habitat'] = habitat;
  return animal;
}

console.log(addHabitat(tiger, 'Rainforest'));
// User Editable Region

they do the same thing

using the square bracket syntax offers more flexibility that the dot notation does not have

obj["name"] // string  - equivalent of obj.name
obj["first name"] // string with space
obj[5562] // number
obj[prop] // variable

only the first one has an equivalent dot notation, the others aren’t things that dot notation can do
