I feel like this might be introducing too much. It's not just iteration, it's also introducing:

present?, empty?, any?, all?, none?, one?

count

sort_by

I would have expected this exercise to be about each and times and possibly map and reduce.

+Both the `Array` and `Range` classes in Crystal include the [`Enumerable`][enumerable] module, which provides a number of methods for iterating over the elements.
+Meanwhile, the `String` class has its own set of methods for iterating over the characters.
+
+Crystal also doesnt have any any for statement like other languages.

+
+The most common way to iterate over a collection is to use the [`each`][each] method, which yields each element in the collection to a block.
+This can be done easily with a `Range`.
+Say you would want to loop between 1 and 3, you can use the `each` method to iterate over the range.

+A `String` is a sequence of characters, and doesnt belong to the `Enumerable` module, which means it has its own set of methods for iterating over the characters.
