Convert strings between camelCase, PascalCase, Title Case, snake_case,
lowercase, UPPERCASE, CONSTANT_CASE and more.
All methods support Unicode (non-ASCII characters) and non-string entities, such
as objects with a toString property, numbers and booleans. Empty values
(null and undefined) will result in an empty string.
