4. Of Objects and Classes
 JavaScript is full of objects
 Ex: Array in JavaScript is an object with values and also
methods like push, reverse, and pop
 Where does a method like push come from?

5. Of Prototypes
 Every object in JavaScript holds a hidden piece of
state __proto__
 How can we grab that reference ?
Object.getPrototypeOf(point) != Object.getPrototypeOf(myArray);

10. Of Functions
 Functions in JavaScript are objects
 Every function object in JavaScript has a prototype
property
 Do not confuse this prototype property with the
__proto__ property – they do not serve the same
purpose or point to the same object.

12.  Imagine we want to create a new object and make the
new object behave like an array

13. Constructor Functions
 The first letter of a constructor function is
capitalized by convention
 A constructor function expects to be used in
conjunction with the new operator to construct
objects.
