|

// for (items) |item| {
|

|

// // Do something with item

// Note that 'for' loops also work on things called "slices"
|

// which we'll see later.
|

|
|
// Also note that 'for' loops have recently become more flexible
|
|
// and powerful (two years after this exercise was written).
|
|
// More about that in a moment.
