Javascript Basic Concepts Summary

Summary from The Principles of Object-Oriented Javascript BY Nicholas C. Zakas

I. Constructor & Prototypes
  Generic objects (created via and object literal or the Object constructor): constructor -> Object.
  Objects created with a custom constructor: constructor -> points back to constructor function.
  With constructor, 200 instances have 100 copies of a function.

II. Module Pattern
    Module Pattern: an object-creation pattern, creates singleton objects with private data
    IIFE (immediately invoked function expression): a function expression that is defined and then called immediately to produce a result.
    Revealing Module Pattern:
    Pseudoclassical inheritance: minxin -- copies properties from one object to another so that the receiving object gains functionality without inheriting from the supplying object.
    Prototypal inheritance:
 Scope-safe constructor
