CodePen showcasing the mobile navigation
Upon initial interaction with the mobile navigation, it operates as expected. However, a bug arises with subsequent interactions. The navigation either opens and closes instantly or the links appear in a jumbled order.
My goal is for the mobile navigation to smoothly open from right to left, displaying each link in sequence, starting with About and ending with Blog. I also want the reverse animation to occur when the navigation is closed.
Currently, I have not implemented the logic for the reverse animation as I need to address this bug first.

- My suspicion is that the issue lies within the first
ifstatement in thebarsevent-handler. It seems to be waiting for thetransitionendevent without callingstartNavAnimationfirst.
