Why my code is behaving weirdly?

Question

https://sololearn.com/compiler-playground/W2E5bF7iFB4v/?ref=app

In this code when i click on the last song (ur name). It's causing error. But when i click on that song AFTER i already clicked on any random song besides ur name. Then it works fine. Why is that?

Answer 1

Did you fix it? It seems fine when I run it and immediately try the last song.

If it is still a problem, then a debugging technique that you might try is to move the last song elsewhere in the list and see whether the bug moves also.

I didn't do anything but i realised it's probelm with my phone. Cuz it was throwing "user gesture" error on last and second last songs. Which means that i didn't click it properly....(But i did)

But yeah it's working fine now.
