Change Case

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.

Every method is also available on npm as an individual package.
