/* The for principles of "this";
* in your own words. explain the four principle for the "this" keyword below.
*
* 1.
* 2.
* 3.
* 4.
* 1. Global - without context, `this` is in the context of either the Global or Window object
* 2. Implicit - when using an object method, `this` context is implied to be the object left of the dot
* 3. New - when using a constructor, `this` context is of the object built by the constructor
* 4. Explicit - when using bind/apply/call, `this` context explicitly defined.
"half stretch" answer to all 4: `this` generally refers to the parent context of where it's used.
In the case of Explicit, the value of `this` is overridden to be what you give it.
(give example of something about Array())
*
* write out a code example of each explanation above
