Groovy is a powerful, optionally-typed dynamic language for the JVM with static-typing and static compilation capabilities.

Key Features:

• Runs on the JVM
• Java-compatible
• Dynamic and static typing
• Closures
• DSL capabilities

Hello World:

println "Hello, Groovy!"

Variables:

def name = "Groovy"
def age = 20
def isJVM = true
String typed = "Explicit type"

Collections:

def list = [1, 2, 3, 4, 5]
def map = [name: "Alice", age: 30]
