Lecture 201:- Why Prototypes
Prototypes are used in JavaScript to implement inheritance and object composition in an efficient and flexible way.
When we create an object in JavaScript, it has a prototype object associated with it, which is a template object that provides the object with properties and methods that can be inherited. The prototype object contains a set of properties and methods that are shared among all the instances of that object.
Using prototypes, we can add properties and methods to an object without modifying its constructor function. This makes it easier to add or remove functionality from an object at runtime, and also allows us to create new objects based on existing ones, without duplicating their properties and methods.
In addition, prototypes allow for efficient memory usage, since multiple instances of an object can share the same prototype object, rather than each having their own copy of the same properties and methods.
Overall, prototypes are an important concept in JavaScript that enable efficient and flexible object-oriented programming.
