+-   [`67858b3`](https://github.com/stdlib-js/stdlib/commit/67858b341e920fed871e34ba0d6b6809804916f7): improve type safety
+-   [`67858b3`](https://github.com/stdlib-js/stdlib/commit/67858b341e920fed871e34ba0d6b6809804916f7): The return types are now more specific. This may break existing code that relies on less strict typing, but should not affect most users. To preserve the prior behavior, you can cast the return value to `string` via a type assertion.
