 This task focuses on getting practice with callback functions by giving you an array of values and instructions on what to do with that array.
 
-* [ ] Review the contents of the [callbacks.js](assignments/callbacks.js) file.  Notice you are given an array at the top of the page.  Use that array to aid you with your callback functions.
+* [ ] Review the contents of the [callbacks.js](assignments/callbacks.js) file.  Notice you are given an array at the top of the page.  Use that array to aid you with your functions.
 
-* [ ] Write out each function using the `ES5`  `function` keyword syntax.

-* [ ] Solve the problems listed.  Save the stretch problems until you have completed Tasks 1-4.

 ## Task 3: Array Methods
 
 Use `.forEach()`, `.map()`, `.filter()`, and `.reduce()` to loop over an array with 50 objects in it. The [array-methods.js](assignments/array-methods.js) file contains several challenges built around a fundraising 5K fun run event.

 ## Task 4: Closures

 ## Stretch Goals
 
-* [ ] Arrow Function Syntax - [Check out this awesome guide for ES6 arrow syntax](https://medium.freecodecamp.org/when-and-why-you-should-use-es6-arrow-functions-and-when-you-shouldnt-3d851d7f0b26). You will see more and more arrow functions as you progress deeper into JavaScript. Use the [stretch-function-conversion.js](assignments/function-conversion.js) file as a helper challenge to showcase some of the differences between ES5 and ES6 syntax.

+* [ ] Go back through the stretch problems that you skipped over and complete as many as you can.
 * [ ] Look up what an IIFE is in JavaScript and experiment with them
