13-13: Consider adding unit tests for the corner cases.While you've added tests for common scenarios, it would be valuable to add tests for edge cases, such as:
- Nested arrays
- Arrays with
nilelements- Empty arrays
- Very large arrays (to test performance)
This would ensure the robustness of the new implementation across all possible scenarios.

4-4: Great job adding reflect package for deep equality checks.Incorporating
reflect.DeepEqualis the right approach for comparing complex data structures like slices.
10-11: Test cases nicely expanded to handle arrays.The updated test cases for
ToLowernow correctly test both single values and collections, covering various scenarios such as arrays of strings, slices of strings, and mixed arrays.Also applies to: 19-21
26-26: Great switch to reflect.DeepEqual for comparison.Using
reflect.DeepEqualinstead of simple equality is necessary for properly comparing slices and arrays.
34-35: Comprehensive test cases for ToUpper transformation.Test cases now thoroughly validate the function's ability to handle arrays and slices with appropriate expected outputs.
Also applies to: 43-45
58-59: Thoroughly testing Trim with various input types.The test cases for
Trimnow properly cover both single values and collections, ensuring the transformation works correctly in all cases.Also applies to: 67-68
81-82: Complete coverage for RemoveSpecialChars transformation.Tests now validate both individual strings and collections, ensuring special characters are properly removed in all scenarios.
Also applies to: 88-89
102-103: Good test coverage for ToTitleCase with arrays.The test cases effectively validate that ToTitleCase works correctly on both individual strings and collections of strings.
Also applies to: 111-112
125-126: Comprehensive tests for ToInt transformation.Tests now verify the function's ability to handle arrays and slices of convertible values, mixed arrays, and edge cases.
Also applies to: 131-133
146-147: Thorough test coverage for ToFloat transformation.Test cases effectively validate conversion of various input types including array handling capabilities.
Also applies to: 152-154
168-169: Well-structured tests for Truncate function.Tests now properly validate the function's ability to handle both single values and collections.
Also applies to: 174-175
189-190: Complete test scenarios for Replace transformation.Test cases cover all important scenarios including multiple replacements and handling of arrays and slices.
Also applies to: 196-197
239-239: Consistent type updating throughout the codebase.The migration from
interface{}toanyhas been consistently applied across the codebase, including in the validation test cases.Also applies to: 244-244, 252-252, 260-260, 268-268, 276-276

4-4: Good addition of the reflect package.The reflect package is appropriately imported to support the new array handling functionality.
28-36: Clean refactoring of ToLower with array support.The function now elegantly handles both single values and arrays through the helper function.
38-46: Well-implemented ToUpper transformation.The function now supports both single values and arrays using a consistent pattern.
48-56: Good implementation of Trim function.The transformation now correctly handles both individual strings and collections of strings.
58-72: Clean implementation of RemoveSpecialChars.The function now handles array inputs while maintaining the original character filtering logic.
74-83: Well-structured ToTitleCase implementation.The transformation correctly applies title casing to both individual strings and collections.
85-98: ToInt properly handles arrays and different types.The function now correctly transforms both individual values and collections, maintaining type checking.
100-113: Comprehensive ToFloat implementation.The function correctly handles conversion of different types and now supports arrays.
115-127: Truncate function cleanly adapted for array support.The transformer now properly handles both individual strings and collections of strings.
129-139: Replace transformer elegantly handles arrays.The implementation correctly applies string replacement to both individual values and collections.
