- 1: program finished - 2: Cannot predict the order - 3: program finished, promise finished - 4: promise finished, program finished

##### Answer: 3 Even though a promise is resolved immediately, it won't be executed immediately because its .then/catch/finally handlers or callbacks(aka task) are pushed into the queue. Whenever the JavaScript engine becomes free from the current program, it pulls a task from the queue and executes it. This is the reason why last statement is printed first before the log of promise handler. Note: We call the above queue as "MicroTask Queue"
