Object-oriented programming is an important feature of JavaScript. This course will explore the advantages and implications of object-oriented programming, and prepare the learner to create and utilize user-defined objects in JavaScript. It will also introduce key objects that are part of the JavaScript language, including String, Math, Number, and Date objects, as well as arrays. The course will survey common methods and contexts for using these native objects. This course is one of a series covering the fundamentals of the JavaScript language.
