The most sophisticated data type in JavaScript is an object. Any composite data, including data with multiple values, and actions taken on them are described using this. Nearly everything, including arrays, functions, and the browser, can represent an object in JavaScript. Arrays and functions are also considered to be objects. The goal of this course is to introduce objects as data storage associative arrays.
