 ## Task 2: Higher Order Functions and Callbacks
 
 This task focuses on getting practice with higher order functions and callback functions by giving you an array of values and instructions on what to do with that array.

 ## 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.
