Creating Tuples

A tuple groups a fixed number of values together, even when those values have different types.

Unlike a list, where every element shares one type, a tuple can hold an Int, a String, and a Boolean all at once.

Tuples are perfect for returning or bundling a handful of related values without writing a whole class.

You build a tuple by wrapping comma-separated values in parentheses.

Here we pair a name with an age. Scala figures out the types automatically.
