 * **Mini Challenge**: write a function that takes an array and a function as arguments. The function should return a new array that maps every element of the input array by passing it through the function you received. You are not allowed to use `Array.map` for this challenge, otherwise it would be too easy :)
 
 ## Challenges
-Each challenge should be done in a different branch, **branched off of master**. Give the branch a descriptive name of your choice, and make a pull request when you are done:
+Create a branch called `challenges` **off of master**. Make a pull request immediately and push your code after doing each exercise
 
 ### The Fortune Teller
 Challenge: create a file called `fortune.js` in your Cloud9 project. Running this file should output a random quote from a list of 10 different quotes. Make sure to add/commit this file and push it to your GitHub.
 
 ### The Cow Whisperer
-Challenge: create a file called `cowsay.js` in your Cloud9 project. Running this file should output a cow saying a random fortune. Make sure to add/commit this file and push it to your GitHub. If the fortune is longer than 30 characters, you have to wrap it on a new line. For extra brownie points, wrap your fortune at the word level instead of the letter level.

 ### The Penniless Gambler
 Challenge: create a simple HTML file that will only be used for the purposes of running JavaScript in the browser. Create a `guess.js` file and add it to a `<script>` tag of your HTML file. This is simply so you can load your HTML file in the browser and do the challenge: creating a number guessing game.
 
-Generate a random number between 1 and 100. Using the browser functions prompt and alert, ask the user to guess the number. You should give them 4 tries to guess the number. If they guess right, congratulate them. Otherwise, give them a message saying what the correct number was, as well as their list of guesses.

 ### The God of Cows
 **EXTREME** challenge: create a file called `real-cowsay.js` inside your Cloud9 project. This is the only challenge that will require usage of some NodeJS functionality. This program will look more like the regular cowsay. Instead of outputting a random fortune like the previous example, it will either take a string on the command line and output that string (with the cow). If no string is provided on the command line, then your program will use standard input (like the regular cowsay) to get its phrase. Here are a couple of hints that will help you complete this:

 For the standard input version, you will need to read about `process.stdin` as well as learn about asynchronous programming. These are things that will be viewed in week 2 of the course, but if you want to complete the challenge you need to do it :) Here is a link to some initial documentation:
