Incorrect value shown after using pop() in the video "Remove Elements From an Array" by Guil Hernandez.

Hi! I would like to bring awareness to a possible mistake in the video to hopefully obtain an exterminator badge.

In the following statement shown in the video around 30-40 seconds:

let lastItem = shoppingList.pop();

lastItem should hold the value "coffee", not "honey". Since, pop() removed "coffee". The next example of shift() is correct.

You forgot to identify the course, but assuming it's JavaScript Arrays, then at time index 00:38 in the Remove Elements From an Array lesson the 4-element array example changes to a new one showing a 3-element array. The last item in the array is "honey".

I'm not sure why they changed the example, and I also find it a bit confusing, but given the new example code the result of "honey" is indeed correct.

Also, instead of posting to the forum, the procedure for making content suggestions (and also for qualifying for the exterminator badge) is to submit your comments directly to the staff as described on the Support page. You could still let them know about the confusion if you want.

Thank you for your response. In that case, in the new example with "honey", the video should have visually removed "honey" from the array in a similar manner to the "coffee" and "bread" examples. It can cause confusion. I think this was an oversight and thus bug to report. I'll send an email to support.

It's definitely awkward to have the example change the first time by removing the last item, and then change it the second time by putting it back in.   :see_no_evil:
