Generator - yield is used to pause and resume a generator function
- converting a generator to an array (using
Array.from) resumes the generator until all values are received
after the first generator.next() call
- the value is "hello"
- and
done is false
after the second next() call
value is "world"- and
done is still false
after stepping past the last element, calling next() that often
done property equals true, since there is nothing more to iterator over
