 ## Calling an iterator explicitly
 
 Normally, internals of iterables are hidden from the external code. There's a `for..of` loop, that works, that's all it needs to know.
 
-But to understand things a little bit more deeper let's see how to create an iterator explicitly.

 We'll iterate over a string the same way as `for..of`, but with direct calls. This code gets a string iterator and calls it "manually":
