🙃 CaseIn

🔄 Simple and fast utility to flip string case.

Convert a dash/underscore/space separator to Capital Case, camelCase, PascalCase, lowercase, UPPERCASE, Title Case, CONSTANT_CASE, Header-Case and Sentence string.

Empty values (null and undefined) will result in an empty string.
Any extra space will be removed.

Example: ' hello      world ' -> 'hello world'
