Prototype.js application

In prototype.js, prototype object is an important mechanism for implementing object-oriented.

Each function (Function) is an object, the function object has a sub-object prototype object, and the class is defined in the form of a function. Prototype represents the prototype of the function, as well as a collection of members of a class.

When you create an instance object of a class through new, the members of the prototype object become members of the instantiated object.

1. The object is referenced by the class, and only function objects can be referenced.

2. After the new is instantiated, its members are instantiated and the instance object can be called.

At the same time, a function is an object. If a function object declares a member directly, it can be called without being instantiated.
