122. Iterable

The code above outputs the following:

1

The entries method is used to create an iterator object for the array [1,2,3,4]. In the first loop, the break statement is encountered after logging the first item, so the loop is interrupted after the first iteration. Therefore, only the first item (1) is logged to the console.

In the second loop, the break statement is encountered again after the first iteration. However, since the iterator object was already exhausted in the first loop, there are no more items left to iterate over. Therefore, nothing is logged to the console.
