Summary

In this chapter, you learned quite a few ways (patterns) of implementing inheritance, and the following table summarizes them. The different types can roughly be divided into the following:

• Patterns that work with constructors
• Patterns that work with objects

You can also classify the patterns based on whether they:

• Use the prototype
• Copy properties
• Do both (copy properties of the prototype):

#	Name	Example	Classification	Notes
1	Prototype chaining (pseudo-classical)	Child.prototype = new Parent();	Works with constructors Uses the prototype chain	The default mechanism Tip - move all properties/methods that are meant to be reused to the prototype, and add the non-reusable as own properties
2	Inherit only the prototype	Child.prototype = Parent.prototype;	Works with constructors Copies the prototype (no prototype chain, as all share the same prototype object)	More efficient; no new instances are created just for the sake of inheritance Prototype chain...
