+Last Commit Date: Dec 12, 2016
+
+More fun with Array methods! Much like the previous Array Cardio exercise, the 
+  requirements are pretty well documented. This exercise utilizes the following
+  built-in Array methods:
+- [Array.prototype.some()](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/some)
+- [Array.prototype.every()](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/every)
+- [Array.prototype.find()](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/find)
+- [Array.prototype.findIndex()](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/findIndex)
+
+Learn 'em, tuck 'em away in your back pocket, remember where they are and what they do!
