Objects
Definition: Objects in Javascript are used to group related data and functions together. Each piece of data inside an object is called a property.
Syntax:
var myComputer = { // variable is assigned to object starts with a curly brace
operatingSystem: 'Mac', // each property starts with a property name, semicolon, property value in quotes if string. Each property is separated by a comma
screenSize: '15 inches',
purchaseYear: '2011'
}; // ends with a curly brace. The last object ends with a semicolon
