Getting Started with Scala: Your First Snippet

1 min read
A friendly Scala intro for developers who just want to write their first few lines of code.
Scala might look intimidating at first, but let’s change that — one clean snippet at a time.
👋 Why Scala?
Scala combines the power of object-oriented and functional programming in one language. It runs on the JVM, making it a great fit for scalable, high-performance apps — but more importantly, you can just start small.
🛠️ Let’s Get Started — A Simple Hello World
Here’s how you write your first Scala program:
object HelloWorld {
def main(args: Array[String]): Unit = {
println("Hello, Scala!")
}
}
🧠 What’s Happening?
object
is a singleton — like a class with only one instance.main
is the entry point (just like in Java).println(...)
prints to the console.
✅ To run this:
- Use the Scala REPL (via terminal or sbt console)
- Or paste it into Scastie: https://scastie.scala-lang.org and press ▶️
Run
. That’s it!
