Unlike dynamic languages where JSON is trivially a hash map, Scala&rsquo;s type system demands compile-time safety and principled encoding/decoding. In this article, we compare four of the most popular Scala JSON libraries — <strong>Circe</strong>, <strong>Play-JSON</strong>, <strong>Spray-JSON</strong>, and <strong>Argonaut</strong> — examining their APIs, type-safety guarantees, performance characteristics, and integration with popular frameworks.</p>
