+### vowelOne
+
+Write a function that takes a string and outputs a strings of 1's and 0's where vowels become 1's and non-vowels become 0's.
+
+All non-vowels including non alpha characters (spaces,commas etc.) should be included.
+
+Examples:
+
+```haskell
+vowelOne "abceios" -- "1001110"
+
+vowelOne "aeiou, abc" -- "1111100100"
+```
+
+```javascript
+vowelOne('abceios'); // "1001110"
+
+vowelOne('aeiou, abc'); // "1111100100"
+```
