Disparity offers a concise and flexible way to compare two JavaScript values, determining the exact differences between them. Unlike simple equality checks, it dives deep into nested objects and arrays, highlighting additions, deletions, and modifications. Ideal for debugging complex data structures or generating detailed diff reports, Disparity enhances testing and development by providing granular insights into data changes. Its clear output helps pinpoint discrepancies and understand how data evolves over time, improving code quality and reducing debugging effort.
