It’s interesting in this example that the docs try to show that a for loop is useful, when there’s already an idiomatic approach here:
```
const result = items.map(
i => i.length
? i.toUpperCase()
: ‘<empty>’)
```
I think things get interesting here when different kinds of iterators come into play (eg generators, async-await for loops, non-array iterables). Shame the landing page doesn’t touch on that at all.
