 * In class we will be going over the principles listed above and you will be expected to follow along when the instructor asks you to do so.
 
 ### Recursion
+#### What it is
 * recursion is another way to represent a looping program. 
 * Simliar to a `for loop` or a `while loop` a recursive function will loop until you tell it to stop. 
 * when solving complex algorithms recursion comes in handy. It is not that great for smaller, less complex algorithms.
- * For every recursive function, you'll need to establish what is called a `base case`. A `base case` is a condition that when triggered, will discontinue the call to your function.

+### The "this keyword
+* Because JavaScript is both an Object Oriented and Functional Programming language, it has some very interesting concepts built into it.
+* The 'this' keyword is one of those querky concepts that tend to trip up a lot of people coming into JavaScript.
+* You can think of this, as a Pointer to an object. For example, you can use the this keyword to reference an object without having to refer to that object's name.
+* **example**
+```
+  const myObj = { 
+    name: 'Freddy' 
+    greet: function() {
+      console.log(`hello my name is ${this.name}`);
+    }
+  };
+  myObj.greet();
+```
+* In the above example the "this" keyword becomes active when a person's name is called. 
+* Tyler McGinnis' four rules to the 'this' keyword. [found here](https://www.youtube.com/watch?v=zE9iro4r918)
+  1. Window Binding
+  2. Implicit Binding
+  3. New Binding
+  4. Explicit Binding
