- 1: 1, 2, 3 - 2: 1, 3, 2 - 3: 3, 1, 2 - 4: 3, 2, 1

##### Answer: 4 When the JavaScript engine parses the above code, the first two statements are asynchronous which will be executed later and third statement is synchronous statement which will be moved to callstack, executed and prints the number 3 in the console. Next, Promise is native in ES6 and it will be moved to Job queue which has high priority than callback queue in the execution order. At last, since setTimeout is part of WebAPI the callback function moved to callback queue and executed. Hence, you will see number 2 printed first followed by 1.
