Is java script an object oriented programming language or an object based programming language?

Answer 1

That depends on who you ask. An Object Oriented Programming Language is one that allows or encourages, to some degree, object-oriented programming techniques such as encapsulation, inheritance, modularity, and polymorphism. -

http://en.wikipedia.org/wiki/Object-oriented_programming_language * Encapsulation - or "information hiding" is the principal of hiding design decisions which are most likely to change thus protecting other parts of the programfrom change if the design decision is changed. * Inheritance - is a way to form new (derived) classes of objects from pre-existing (base) classes of objects. * Modularity - Allows for developing software which is composed of separate parts * Polymorphism - Allows for values of different data types to be handled using a uniform interface (e.g. num + num = num, string + sting = string, list + list = list, etc)

JavaScript is a prototype based object oriented programming language, as opposed to other languages (such as Ruby) which are class based object oriented programming languagesPrototype-based programming is a style of object-oriented programming in which classes are not present, and behavior reuse (known as inheritance in class-based languages) is performed via a process of cloning existing objects that serve as prototypes. This model can also be known as class-less, prototype-oriented or instance-based programming.

Answer 2

Every single piece of code and data must reside in a class, so it is, in the strictest sense, object-based. However, all object-based languages would also fall in the category of object-oriented programs as well.

Answer 3

Yes it is .

The language providing the facility to create classes and programming via objects are known as object oriented language.

But it is not pure object oriented language.
