-## Project Set up
-
-Follow these steps to set up and work on your project:
-
-- [ ] Create a forked copy of this project.
-- [ ] Add PM as collaborator on Github.
-- [ ] Clone your OWN version of Repo (Not Lambda's by mistake!).
-- [ ] Create a new Branch on the clone: git checkout -b `<firstName-lastName>`.
-- [ ] Create a pull request before you start working on the project requirements.  You will continuously push your updates throughout the project.
-- [ ] You are now ready to build this project with your preferred IDE
-- [ ] Implement the project on your Branch, committing changes regularly.
-- [ ] Push commits: git push origin `<firstName-lastName>`.
-
-Follow these steps for completing your project:
+2. What is the difference between a function and a method?
 
-- [ ] Submit a Pull-Request to merge <firstName-lastName> Branch into master (student's  Repo).
-- [ ] Add your Project Manager as a Reviewer on the Pull-request
-- [ ] PM then will count the HW as done by  merging the branch back into master.
+    A method is a part of an object. It can be called using the object itself. Like person.speak(). Whereas a function is standalone. 
 
+3. What is closure?
 
-## Minimum Viable Product
+    Closure is the term used to describe the scope of individual functions and were they are able to search for the variables they need. 
 
-Your finished project must include all of the following requirements:
+4. Describe the four rules of the 'this' keyword.
 
-**Pro tip for this challenge: If something seems like it isn't working locally, copy and paste your code up to codepen and take another look at the console.**
+    Global Binding. when referencing this in global scope. You are referencing the window/browser/console object that contains all of the parameters, attributes of the window/browser/console.
 
-## Task 1: Objects and Arrays
-Test your knowledge of objects and arrays. 
-* [ ] Use the [objects-arrays.js](challenges/objects-arrays.js) link to get started.  Read the instructions carefully!
+    Implicit Binding. If you have a function within an object, when you call that function outside of the object, like: aaron.myFunction(), the object aaron is what this. references. 
 
-## Task 2: Functions
-This challenge takes a look at callbacks and closures as well as scope. 
-* [ ] Use the [functions.js](challenges/functions.js) link to get started. Read the instructions carefully!
+    Explicit Binding. Similarly to implicit, however the binding is visible and external. Whereas implicit is hidden. 
 
-## Task 3: Prototypes
-Create constructors, bind methods, and create cuboids in this prototypes challenge.
-* [ ] Use the [prototypes.js](challenges/prototypes.js) link to get started. Read the instructions carefully!
+    New Binding. When creating new functions or objects. Using the this keyword basically refers to the object that is being created. So each this.something is now an attribute being created in the object. 
 
-## Task 4: Classes
-Once you have completed the prototypes challenge, it's time to convert all your hard work into classes.
-* [ ] Use the [classes.js](challenges/classes.js) link to get started. Read the instructions carefully!
+5. Why do we need super() in an extended class?
 
-In your solutions, it is essential that you follow best practices and produce clean and professional results. Schedule time to review, refine, and assess your work and perform basic professional polishing including spell-checking and grammar-checking on your work. It is better to submit a challenge that meets MVP than one that attempts too much and does not.
+    Super() is an abstraction of creating the parent objects. Passes the attributes back up to the parent class so that the object created can have same attributes as parents.
