Updated the logic here to ensure that the divider only shows for the conditions below.

One question (and maybe this could be cleared up in a demo), but the image included in the PR shows that the last message is hidden behind the message text field. Is the auto scroll behavior not working as expected now? I would expect the message to not be hidden behind the field. Thanks! |
@alangsto ah yes! This is just because I had to scroll up to see the divider. It does still auto scroll as expected. Happy to demo to show how it works or even just add a screenshare. |

This is not a blocking feedback. That said, why can't a open source library like moment.js help you here?

IMHO, I'm not fully agree on adding a library to the bundle and dependencies just for something trivial, but I understand the point.
If we don't add the dependency, we might want to compare dates as strings to make it a bit simpler.
const now = new Date()
const isToday = (now.toDateString() === otherDate.toDateString());Just leaving it as an alternative.

Thank you both! So part of the issue with comparing the dates as strings is that these are timestamps. So I would need to extract the date only first and compare those strings.

Simon, to your point, I did look in frontend-app-learning to see if something similar was implemented and I did see this: https://github.com/openedx/frontend-app-learning/blob/master/src/course-home/dates-tab/utils.jsx. I wonder if there was a reason that we didn't just use another library there; I wonder if for a similar reason as what Marcos suggested?

This is how custom code proliferate. Some engineer think the custom code at that time is a good idea, then it gets accepted. Others later would find it to be acceptable too. I get it. This is why my question here is not a blocking feedback.

That's true. I'll do some quick research on moment.js and make the call soon to merge.

Okay so I went to moment.js and see an article suggesting more modern alternatives: https://momentjs.com/. Maybe for times sake I'll move forward as is though this isn't the ideal. Thanks for the feedback in any case.
