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

+```js
+const toTitleCase = str =>
+  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.charAt(0).toUpperCase() + x.slice(1))
+    .join(' ');
+```
+
+```js
+toTitleCase('some_database_field_name'); // 'Some Database Field Name'
+toTitleCase('Some label that needs to be title-cased');
+// 'Some Label That Needs To Be Title Cased'
+toTitleCase('some-package-name'); // 'Some Package Name'
+toTitleCase('some-mixed_string with spaces_underscores-and-hyphens');
+// 'Some Mixed String With Spaces Underscores And Hyphens'
