prototypal inheritance VS classical inheritance

[WHAT]

1. ] prototypal inheritance VS classic al inheritance
1. ] prototypal inheritance is a method of inheritance we (should/could) use in the javascript programming language to create new objects by 'inheriting' charactistics of existing objects
2. ] classical inheritance is used in many common programming languages like c++, java
2. ] classical inheritance - has 2 seperate/distinct entities for object creation and object usage,
1. ] the 'class' - A class is the 'template' for 'an object' that defines the object instances properties and methods(behaviour), objects use constructor methods to create new instances of the object  
2. ] the 'instance' - work with 'an instance' of the class - your object variable - a single instance of the var, EX var don = new Person()
3. ] prototypal inheritance -
1. ] Prototypal inheritance is all about objects. Objects inherit properties from other objects. That's all there is to it.
2. ] Constructors never come into the picture. 
3. ] ??? The "constructor pattern" of prototypal inheritance. Unfortunately JavaScript uses the constructor pattern of prototypal inheritance ???
4. ? is Crafting your own constructors for producing custom objects,
5. ? also sets up prototypal inheritance for "your object()"instances.,
6.  There are two ways of creating objects using prototypal inheritance:

[WHY reasons]  

1. ] prototypal pros
2. ] prototypal cons
3. ] classical pros
4. ] classical cons
