+####Description:
+
+Check that the two provided arrays both contain the same number of different unique items, regardless of order. For example in the following:
+    [a,a,a,a,b,b] and [c,c,c,d,c,d]
+Both arrays have four of one item and two of another, so balance should return true.
+
+####Example:
+
+```js
+let array1 = ["a","a","a","a","a","b","b","b"],
+    array2 = ["c","c","c","c","c","d","d","d"];
+
+    balance(array1, array2) //true
+
+    array1 = ["a","a"],
+    array2 = ["c"];
+
+    balance(array1, array2) //false
+
+    array1 = ["a","b","c","d","e","f","g","g"];
+    array2 = ["h","h","i","j","k","l","m","m"];
+
+    balance(array1, array2) //false
+```
