+Converts a string to kebab case.
+
+- Use `String.prototype.match()` to break the string into words using an appropriate regexp.
+- Use `Array.prototype.map()`, `Array.prototype.join()` and `String.prototype.toLowerCase()` to combine them, adding `-` as a separator.

+  str
+    .match(/[A-Z]{2,}(?=[A-Z][a-z]+[0-9]*|\b)|[A-Z]?[a-z]+[0-9]*|[A-Z]|[0-9]+/g)
+    .map(x => x.toLowerCase())
+    .join('-');
