Which Javascript function can be used to play more than one audio simultaneously?

I am thinking to make [https://moodly.site/.
I can add one audio and can make users play it on-click but how to make 1+ audio to be played.I am not sure, can I make it with just Vanilla JS or I need to work with any framework.

Is there any tag in HTML which can allow me to do this or it is solely JS’s part?
