Ratpack VS groovy

There are a huge set of web frameworks in Java that have the same example as shown on this site; I have no idea how this differs from, say, https://ratpack.io or https://sparkjava.com. This really needs some key features on the site to sell it.

Ratpack is also the name of a Java web framework - https://ratpack.io

If you want something really small that simply let's you expose REST APIs using plain Java, without the IoC containers, you might want to check out Javalin, Ratpack or Armeria

This time, I visited Groovy. Given my biased first impression about Java and the JVM, I wasn't too exited! But I couldn't have been more wrong! 😁

The default programming language is Kotlin instead of Java. Also, Build configuration language is nowadays Kotlin DSL (build.gradle.kts) instead of Groovy DSL (build.gradle), the past default.

There are languages that are more like "script versions of java", lately including java itself - you can run simple .java stuff directly with a shebang line now - but things like Beanshell of yore and Groovy are far more java-like than javascript.

Install Groovy: To use Groovy, you'll need to first install it. You can find the installation instructions on the Groovy website (https://groovy-lang.org/)

On https://groovy-lang.org a lot of big companies are listed which use(d) Groovy. Is this still current? E.g. Netflix, ...

Groovylang

Hence, Groovy

If you want the power of JAVA but the feel of PYTHON, try Groovy (https://groovy-lang.org/) . Basically a scripting lang for JVM but can be dynamically/statically compiled and is 100% compatible with all JAVA libs but looks like Python

Doesn't Groovy (https://groovy-lang.org) achieve much of this? I remember being taught with it at university for some time before they introduced Java. With Groovy you don't need the class or main method, and can have a program which is just `println "Hello world!"`.
