Object Literals

Objects are collections of key-value pairs (properties).

To create an object we can do as follows:

let person = { firstName: 'Megan', isOnVacation: true, favFoods: ['plum', 'salad', 'fritos']
}

To access values within the object we can:

console.log(person.isOnVacation); // true
console.log(person['isOnVacation']); // true

We can also make an object that contains objects:

let student = { name: 'Jimmy', exams: { artFinal: 'A', mathFinal: 88 }
}

To access a value in the object’s object, we can:

console.log(student.exams.artFinal); // 'A'

Also, we can make arrays containing objects:

let friends = [ { name: 'Sorour', favColor: 'blue', metAt: 'college' }, { name: 'Timothy', favColor: 'red', metAt: 'Starbucks' }
];

To access a value in the second object, we can call:

console.log(friends[1].favColor); // 'red'

To update a value in the second object, we can:

friends[1].name = 'Tim'; console.log(friends[1].name); // Tim
