JavaScript Prototype Design Pattern
Let's continue our discussion about JavaScript Design Patterns. We've already talked about Factory and Builder pattern . Today I'll overview the Prototype pattern . The Prototype pattern creates new objects by cloning one of a few stored prototypes. The Prototype pattern has two advantages: it speeds up the instantiation of very large, dynamically loaded classes (when copying objects is faster), and it keeps a record of identifiable parts of a large data structure that can be copied without knowing the subclass from which they were created. Have a look at the following illustration, depicting the pattern: While there is a lot of information about cloning on the internet and even some suggest using it in the prototype design, the external approach is utterly incorrect. However since we are Object Oriented programmers, we would like to clone both public and private members. None of the external approaches will give you such result. On the other hand, if you will
