 Converts a string to camelcase.
 
-- Break the string into words and combine them capitalizing the first letter of each word, using a regexp.
+- Use `String.prototype.match()` to break the string into words using an appropriate regexp.
+- Use `Array.prototype.map()`, `Array.prototype.slice()`, `Array.prototype.join()`, `String.prototype.toLowerCase()` and `String.prototype.toUpperCase()` to combine them, capitalizing the first letter of each one.
