Frequent question: Why is JavaScript considered to be object based rather than object oriented?

JavaScript is Object-Based, not Object-Oriented. The difference is that Object-Based languages don’t support proper inheritance, whereas Object-Oriented ones do. There is a way to achieve ‘normal’ inheritance in JavaScript (Reference here), but the basic model is based on prototyping.

Why is JavaScript Object-based and not object oriented?

Is JavaScript is object oriented or 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.

Why is JavaScript said to be an object-based programming language?

To be more precise, JavaScript is a prototype based object oriented language, which means it doesn’t have classes rather it define behaviors using constructor function and then reuse it using the prototype.

Is JavaScript object based scripting language?

An example of a commonly used prototype-based scripting language is JavaScript. Both object-based and object-oriented languages (whether class-based or prototype-based) may be statically type-checked.

What is the difference between object-oriented programming and non object-oriented programming?

Both are programming processes whereas OOP stands for “Object Oriented Programming” and POP stands for “Procedure Oriented Programming”. Both are programming languages that use high-level programming to solve a problem but using different approaches.

What is difference between Java and JavaScript?
