No, that function uses the value that was given to the manageAudio() function.
We are instead tracing things backwards, to find out where the information comes from.
The manageAudio() function gets opts.playing from that excerpt of code in my previous post, which uses a variable called
playing in the playButton() function.
Going backwards further from there, the question is of where does that
playing variable in the playButton() function get its value from?
