arrayComparative
ArrayComparative is a concept in data analysis and software engineering that refers to systematic comparisons between arrays or multi-dimensional arrays. It encompasses methods for assessing similarities and differences across data sets, including element-wise checks, structural comparisons, and tolerance-based numeric matching. The goal is to identify exact matches, discrepancies, and the nature of the discrepancies.
Key features include element-wise comparison with a customizable comparator; support for one-dimensional and multi-dimensional arrays; optional
Applications span data validation in ETL pipelines, regression testing to compare expected versus actual outputs, data
Implementation notes emphasize language-agnostic design: library utilities in Python, JavaScript, Java, or as part of testing
