Inheritance

JavaScript is a prototype-oriented language, not an object-oriented programming language. So the concepts of OOP might not be as much clear and easy as in other OOP languages, such as C# or Java. 


So, you can create inheritance in JavaScript following the prototype functions. https://developer.mozilla.org/en-US/docs/Web/JavaScript/Inheritance_and_the_prototype_chain.
