Background

We know what OOPs are and their class-based and/or prototype-based approach. The challenge when using OOPs is creating a general mechanism to generate custom objects. In this lesson, we will use functions to construct objects, also called constructor functions. This is the best approach to implement prototype-based OOPs.

Constructor functions

Constructor functions, or object constructor functions, contain blueprints to a type of object that has properties and methods to generate objects. All objects created from a constructor function will have the same properties and methods but not necessarily the same values.
