Is OOP used in JavaScript?
JavaScript is not a class-based object-oriented language. But it still has ways of using object oriented programming (OOP). The most popular model of OOP is class-based. But as I mentioned, JavaScript isn’t a classed-based langauge – it’s is a prototype-based langauge.
What are JavaScript OOPs concepts?
The basic idea of OOP is that we use objects to model real world things that we want to represent inside our programs, and/or provide a simple way to access functionality that would otherwise be hard or impossible to make use of.
What are the 5 principles of object oriented programming?
SOLID is an acronym for five main principles of Object-Oriented Programming (OOP): single responsibility principle, open-closed principle, Liskov substitution principle, interface segregation principle and dependency inversion principle.

Why is JavaScript not OOP?
Many developers do not consider JavaScript a true object-oriented language due to its lack of class concept and because it does not enforce compliance with OOP principles. So, a language can be Object Oriented if it supports objects even without classes, as in JavaScript.
Why is JavaScript object based?
JavaScript is an object-based language based on prototypes, rather than being class-based. Because of this different basis, it can be less apparent how JavaScript allows you to create hierarchies of objects and to have inheritance of properties and their values.

Is the JavaScript language class based or oop?
JavaScript is not a class-based object-oriented language. But it still has ways of using object oriented programming (OOP). In this tutorial, I’ll explain OOP and show you how to use it. According to Wikipedia, class-based programming is a style of Object-oriented programming (OOP) in which inheritance occurs via defining classes
What are the four principles of object oriented programming?
There are four core principles in object-oriented programming. Without them programming language can’t be called object-oriented. These principles are encapsulation, inheritance, polymorphism and abstraction. In this article, you will learn about these principles, their meaning, and how to use them.
What are the characteristics of object oriented JavaScript?
JavaScript is described as Prototype-based language, to provide an inheritance object that can have a prototype object that inherits methods and properties from other objects. An objects prototype object may also have a prototype object which inherits methods and properties from its parent object and so on; this is called prototype chain.
How does an object access its prototype in JavaScript?
Every object in Javascript has access to the Object ‘s prototype by default. If configured to use another prototype, say prototype2, then prototype2 would also have access to the Object’s prototype by default, and so on.
