Level 20. Tuples: Bundling Values Together

Sometimes you want to keep two (or more) values together, like an x and y position, or a name and an age. A tuple is a tiny bundle that holds several values side by side.

Making a tuple

Wrap values in parentheses, separated by commas:

let point = (10, 20)
let person = ("Alicia", 15)

Getting values out

Use .0 for the first item and .1 for the second:

let point = (10, 20)
println("{point.0}")  // 10
println("{point.1}")   // 20

Think of .0 as “the first pocket” and .1 as “the second pocket”.

Destructuring: opening the bundle

You can unpack a tuple into separate variables with let:

let point = (10, 20)
let (x, y) = point
println("{x}")  // 10
println("{y}")  // 20

This is called destructuring. You “take apart” the tuple and give each piece its own name.

When are tuples handy?

• Returning two things from a function
• Grouping coordinates: (x, y)
• Keeping a pair of related data together without inventing a new type

🎯 Try it: Make a tuple ("Hica", 2026) and print both parts using .0 and .1.
