Scala is like the Swiss Army knife of programming languages, packed with features that can solve almost any problem you throw at it. One of its best-kept secrets? Traits. Think of traits as superpowers you can grant your classes - allowing them to fly, become invisible, or at the very least, reuse code like a boss.
In the Scala universe, traits are like the mixins of the Marvel Cinematic Universe. They allow your classes to inherit behaviors without the drama of multiple inheritance. Traits can contain methods with full-blown implementations or just abstract definitions, waiting for some class to come along and complete the picture.
Let's start with a trait that any superhero would find useful : trait SuperStrength { def lift(tons: Int): Unit = { println(s"Lifting $tons tons with ease. Call me when there's something heavy.") }} This SuperStrength trait is like the Hulk's gym routine.
What's better than one superpower? Multiple superpowers, of course! Scala lets you mix multiple traits into a class, allowing for a highly versatile way of building your superhero or any other class.
