> develop in compared to a host of better languages (Swift, Scala, Groovy, and C# all included Swift, Scala, and C# are statically-typed languages, like Java, whereas Apache Groovy is dynamically-typed originally -- though static typing was added in Groovy 2, virtually no-one uses it. Dynamically typed languages like Groovy are good for glue code, build scripts, and testing, not for developing actual systems.
