Clojure provides powerful abstractions like Protocols and Records for structuring code efficiently.Protocols offer polymorphic behavior and can be extended to existing types dynamically.Records provide a structured, performance-focused alternative to Clojure maps.Clojure blends functional flexibility with structured performance using Protocols and Records.Trait-like features in Clojure Protocols make them versatile for data modeling and more.Implementing Protocols in Clojure differs from Java interfaces in terms of extensibility and performance.Clojure's extension of Protocols to existing types allows seamless behavior enhancement.Records in Clojure offer fast field access and can implement protocols for additional functionality.Creating instances of Records in Clojure provides both fixed and flexible approaches.Using Protocols and Records in Clojure allows for efficient data structuring and dynamic behavior.
