Kotlin for the back-end – Does the fancy code bring much value?
summary
Builds a Spring Boot app twice — using Spring Boot + Kotlin, H2 and Spring Data JPA — creating Person and Note entities, repositories and REST endpoints; live coding shows POST/GET working and associations persisted. Claims Kotlin gives a decent improvement over Java, not a revolution; highlights data classes/extension functions, nullable types to cut NPEs, concise lambdas and let, and mentions Kofu for faster startup and DSL-style configuration.
