Getting Started with Scala: Your First Snippet

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!
