Groovy

ELI5 — The Vibe Check

Groovy is Java with the suit jacket off and sleeves rolled up. It makes Java more fun by adding dynamic typing, closures, and a relaxed syntax. Most people know it as 'the language Jenkins pipelines are written in.'

Real Talk

A dynamic, optionally-typed language for the JVM that enhances Java with scripting capabilities, closures, and a more concise syntax. Groovy is widely used for Gradle build scripts, Jenkins pipeline definitions, and as a testing DSL with Spock framework.

def names = ['Alice', 'Bob', 'Charlie']
def greeting = names
    .findAll { it.length() > 3 }
    .collect { "Hello, $it!" }

println greeting
