+### join
+
+Joins all elements of an array into a string and returns this string. Uses a separator and an end separator.
+
+Use `Array.reduce()` to combine elements into a string.
+Omit the second argument, `separator`, to use a default separator of `','`.
+Omit the third argument, `end`, to use the same value as `separator` by default.
+
+```js
+const join = (arr, separator = ',', end = separator) =>
+  arr.reduce(
+    (acc, val, i) =>
+      i == arr.length - 2
+        ? acc + val + end

+### mask
+
+Replaces all but the last `num` of characters with the specified mask character.

+Use `String.slice()` to grab the portion of the characters that need to be masked and use `String.replace()` with a regex to replace every character with the mask character. 
+Concatenate the masked characters with the remaining unmasked portion of the string.
+Omit the second argument, `num`, to keep a default of `4` characters unmasked.
+Omit the third argument, `mask`, to use a default character of `'*'` for the mask.
