In the creation of Ballerina, we were inspired by many technologies. Thank you to all that have come before us (and forgive us if we missed one): Java, Go, C, C++, D, Rust, Haskell, Kotlin, Dart, TypeScript, JavaScript, Python, Perl, Flow, Swift, Elm, RelaxNG, NPM, Crates, Maven, Gradle, Kubernetes, Docker, Envoy, Markdown, GitHub, and WSO2.
