Script Preparation code:

const delayA = time => new Promise(res=>setTimeout(res,time));
const delayT = (func, wait) => {
    var args = slice.call(arguments, 2);
    return setTimeout(function(){
      return func.apply(null, args);
    }, wait);
  };
var test = function(){
  return;
}

Tests:

delayA
(async function(){ await delayA(0); test(); return; })();
delayT
(async function(){ await delayT(test,0); return; })();
setTimeout
(async function(){ setTimeout(test,0); })();
