Type Inference

Scala can often infer types, reducing boilerplate code.

Examples

val x = 42 // Inferred as Int
val name = "Alice" // Inferred as String
val list = List(1, 2, 3) // Inferred as List[Int]

However, you can still annotate types explicitly when needed:

val name: String = "Bob"

Type inference works well with functions too:

val add = (x: Int, y: Int) => x + y
