 /* The for principles of "this";
 * in your own words. explain the four principle for the "this" keyword below.
 *
-* 1. 
-* 2. 
-* 3. 
-* 4. 
+* 1.  Window/Global Object Binding- When the "this" keyword is in the global scope then it is referring to just that---the global scope object or
+sometimes called the window object.  This is where all of JavaScript is housed.  Generally, this can be avoided by typing in "use strict" at the
+beginning of your code.  
+
+* 2. Implicit Binding- This is the most common use of the "this" keyword & the one that makes the most
+sense to me.  When the "this" keyword is housed inside of an object it is initially referencing that object until another
+function is invoked using the "dot" invoking notation.  Whatever is to the left of the dot is what "this" will now be referencing.  
+
+* 3. New Binding - These are used with constructor functions.  The "this" keyword refers to what the keyword "new" is referencing.   
+
+* 4. Explicit Binding- Similar to new binding in that it can involve the keyword "new"; however, other keywords (call, apply, bind) are used
+to override what the "this"  keyworod is initially pointing to.  
 *
 * write out a code example of each explanation above
