Iterator: usage

create an iterator/iterable

• the usersIterable should be iterable
• the iterator of usersIterable should return an object
• the iterator of usersIterable should have a next function

fill the iterable with content using ConsumableUsers

using the iterator

• should return Alice as first user
• should return Bob as second user
• should return done:true, which means there are no more items

using built-in constructs

• use Array.from() to convert an iterable to an array
• use for-of to loop over an iterable
• use the spread-operator to convert/add iterable to an array
• destructure an iterable like an array
