Since, JavaScript is prototype based, there's no such thing as Class. Output: My name is John Doe and I have 25 years old.Ĭan you please convert this to JavaScript?Īnother question: Can we have polimorphism in JavaScript?

('My name is ' + person.firstName + ' ' + person.lastName + ' and I have ' + person.age + ' years old.') Inside main() Derived person = new Derived('John', 'Doe', 25) Public int age // public scope to simplifyĭerived(String firstName, String lastName, int age) Public String lastName // the same as above Public String firstName // public scope to simplify I've done many attempts to understand OOP in JavaScript without success.Īll articles I've read so far are very confuse and not explain succintly OOP in JSĪs a last attempt to understand OOP in JavaScript, can someone translate to JS the following code, pleas? public class Base
