Prototype Pattern
Explore the prototype creational pattern in JavaScript to understand how objects can be efficiently cloned using prototypal inheritance and the Object.create method. This lesson explains how prototypes serve as blueprints, enabling property sharing and improved performance in object creation.
We'll cover the following...
What is the prototype pattern?
The prototype creational pattern is used to instantiate objects with some default values using an existing object. It clones the object and provides the existing properties to the cloned object using prototypal inheritance.
In prototypal inheritance, a prototype object acts as a blueprint from which other objects inherit when the constructor instantiates them. Hence, any properties defined on the prototype of a constructor function will also be present in the cloned ...
