+#### Options for String Enums:
+
+- `casing`: Transforms the string based on the specified casing style. Available options are `snakeCase`, `camelCase`, `PascalCase`, `kebabCase`, `lowercase`, and `uppercase`.
+- `transform`: Provide a custom function to transform the enum values. This function takes the original value and returns a transformed value.
+
+##### Example:
+
+```
+const { userId, userAddress } = Enum.String({ casing: 'kebabCase' });
+console.log(userId); // Outputs: "user-id"
+
+const options = {
+  casing: 'kebabCase',

+- `step`: Increment the numeric values by a specific step (e.g., 2, 5, 10).
