Js functions

Question

Hey all,

Why does js allow you to call a function again while it's still running whats its purpose?

I'm trying to find a nice way to use ontouchstart on a function that only calls it once until its finished without using timers... I have done it before but the code seems over complicated for somthing simple 🤔

Thank you
