Objects
An object groups related values under names called properties: let pet = { name: "Milo", age: 3 };
Read a property with a dot: pet.name is "Milo". Change one the same way: pet.age = 4;
Objects and arrays work together. A list of products is an array of objects, and that's how most real app data looks.
Example
let book = { title: "Wonder", pages: 310, read: false };
book.read = true;
console.log(book.title + " has " + book.pages + " pages");
console.log("Finished?", book.read);Separate properties with commas, and don't forget the colon between each name and its value.
