Introducing Ballerina: A Pragmatic Programming Language

on YouTube ↗31m

" summary

Demo consumes the World Bank Country API using an HTTP client and maps JSON into Ballerina record types; the compiler's B tool builds self-contained executables and a VS Code plugin runs the demo. The language targets the JVM (current build: Update 9), uses open structural types to describe network payloads, shows sequence diagrams for call flows, and emits compile-time concurrency warnings; explicit error handling with the check keyword returns errors to callers.
