JavaScript has a variety of inheritance patterns, summed up the use of the method is: The prototype chain transfer, the construction function of borrowing, object replication.This article is very clear, let us understand: all JS objects from NULL,

Prototype is a method for a class of objects introduced in IE 4 and later versions, and the special place is: it is a way to add a method to the object of the Class! This may sound a bit messy, don't worry, I will use the example to explain this
