Why do we need to call renderInElement in the onclick functions?

I whonder why we need to call this method on the playButton, stopButton and nextButton. This method creates a list of the songs attached to the #playlist-element. I simply cant follow, why this changes the current state for the songs by clicking on of the buttons.

Thank you

renderInElement updates the html view. the states of our object instances within app.js would be updated (i.e. a song would be stopped or played, and/or the track number would change), but the view wouldn't reflect that, without this method call. it's worth noting that this isn't the most efficient means of doing so, but it works for the purpose of this video series.

i hope this helps!
