+# Context and Tools Lab 02
 
-## To Submit this Assignment
-  * fork this repository & create a new branch for your work
-  * write all of your code in a directory named `lab-` + `<your name>` **e.g.** `lab-susan`
-  * push to your repository
-  * submit a pull request to this repository
-  * submit a link to your PR in canvas
-  * write a question and observation on canvas
+This program leverages array prototype methods to declare stand alone functions used for functional program.
 
-## Directions
-  * create a `/lib` and `/test` directory
-  * add a robust `.gitignore` file
-  * include a `package.json`
-  * include the provided `.eslintrc` file
-  * create a `lint` script for running eslint
-  * create a `test` script for running mocha
-  * create a `lib/fp.js` file for holding the following:
-    * create stand alone `map`, `filter`, `reduce`, `concat`, and `splice` functions using the `call`, and `apply` methods we discussed today
-    * you are welcome to use/experiment with `bind` too!
-  * *note:* - all functions should be created using the es6 lexical arrow function syntax
+##fp.js
 
-# Tests
-  * create a test for each of your custom functions in `lib/fp.js`
-    * note - feel free to create additional tests, if you choose!
-
-## Bonus 2pts
-  * create a CLI (`index.js`) that will use your new `map` function to uppercase all command line arguments and print them to the screen: 1pt
-    * **hint:** - you'll want to check out the `process` object (and it's methods) to get an array of provided command line arguments
-  * test your CLI: 1pt
+  -Builds out stand alone functions map, filter, reduce, concat, and splice.
+  -All functions take an argument of a least one array and can be called in place of using a method.
+  -Several functions require callbacks as well
+  -Each function will throw an error if the necessary  arguments are not passed in.
