When 'this' is used inside an object, it points to the object itself

this-example.js

var dog = {
  name: 'Chester',
  breed: 'beagle',
  intro: function(){
    console.log(this);
  }
};

dog.intro();

// returns the dog object and all of it's properties and methods
// {name: "Chester", breed: "beagle", intro: ƒ}
//    breed:"beagle"
//    intro:ƒ ()
//    name:"Chester"
//    __proto__:Object
