Potential Typo in Iterators & Generators chapter 8

[ronen-e]

In chapter 8 under the section "Iterables and for-of" - there seems to be a typo in the sentence

A for-of loop calls next() on an iterable each time the loop executes

However Iterable objects are not required to implement a next() method.

The for-of loop uses [Symbol.iterator]() on the iterable only to obtain the iterator object and then consume the iterator.

I think the correct terminology is to use iterator instead, like:

A for-of loop calls next() on an iterator each time the loop executes

Yeah, that seems like a typo. Thanks.

Okay, so this one is a bit tricky. The for-of loop technically works on iterables. It creates an iterator for the iterable and then calls next() on that. So the correct sentence might look like this:

A for-of loop works on an iterable and uses its Symbol.iterator property to retrieve an iterator. Then, the for-of loop calls next() on that iterator each time the loop executes and stores the value from the result object in a variable.

@nzakas 👍

btw, glad to hear you're feeling better
