Polymorphism: Polymorphism is one of the core concepts of object-oriented programming languages. Polymorphism means the same function with different signatures is called many times. In real life, for example, a boy at the same time may be a student, a class monitor, etc. So a boy can perform different operations at the same time. Polymorphism can be achieved by method overriding and method overloading
You also learned that using object-oriented programming paradigms and classes in your code has a lot of advantages, from improving application structure and code reusability to reducing code complexity.
Inheritance in object-oriented programming allows developers to define an "is a" relationship between classes. For example, we might want to extend our object model to define slightly more specialized versions of the Pet class: Dog and Cat. The base class, Pet, will contain any properties or methods shared by all Pets, but Dog and Cat may define additional properties or methods applicable only to instances of those classes. For example, our Dog class will provide a wag tail method, and the Cat class will provide a purr method.
Objects are the basic run-time bodies in an object-oriented framework. They may represent a place, a person, an account, a table of data, or anything that the program needs to handle. Objects can also represent user-defined data such as vectors, time, and lists.
The scope of this course extends from covering all the new object-oriented features introduced in ECMAScript 2015 and shows you how to build large-scale web apps that promote scalability, maintainability, and reusability.
Inheritance is one of the major features of object-oriented programming, by which an entity inherits some characteristics and behaviors of some other entity and makes them their own. Inheritance helps to improve and facilitate code reuse.
Learning how to create objects is the first step to understanding object-oriented programming. The second step is to understand inheritance. In traditional object-oriented languages, classes inherit properties from other classes. 041b061a72
