JS Object Type

Overview

All things in JavaScript are objects. JavaScript is an object-oriented language, but JavaScript does not use classes. In JavaScript, classes are not created and objects are not created through classes (as in other object-oriented languages). JavaScript is based on prototype, not class-based.
