I parallelise some functions with spawn and hold(Math.random * 20). What
happens if a pure normal js function scheduled with setTimeout finds the
opportunity to run, while the parallelised functions still run? The pure
function won't run concurrently, right? I am asking because in a game that
I build some function with setTimeout runs and then ends before it
completes, while it would have to complete (probably a bug in my game).

It depends on the details. Let's say the functions that you spawn have the form:

function foo() {
  hold(Math.random*20);
  ...more code, but no hold(), etc...

}

Your pure JS function might execute while foo is blocking in the
hold()-call, or after foo() is finished, but not while 'more code' is
executing (unless 'more code' contains blocking calls as well, such as
hold(), or calls to functions that, in turn, call hold()).

Cheers,
Alex
