What is the iterator and how does it build an ecosystem in Go?

09:05 - 09:45

We would be able to use functions in “for range” in Go 1.23. This feature is known as iterator, you can try it with GOEXPERIMENT=rangefunc in Go1.22. The maps and slices packages provide functions that return or get an iterator in Go1.23. For example, maps.Keys returns an iterator of keys instead of a slice. This session will explain iterators and how to use them. And I will show my thoughts about an ecosystem built around iterators and related functions.
