Refer to the code:
01 console.log( ' Start ' );
02 Promise.resolve( ' Success ' ).then(function(value) {
03 console.log( ' Success ' );
04 });
05 console.log( ' End ' );
What is the output after the code executes successfully?
Answer: C
Explanation:
* console.log( ' Start ' ) runs immediately (synchronous).
* Promise.resolve().then(...) places the callback in the microtask queue. The .then handler does not run immediately.
* console.log( ' End ' ) runs next (still synchronous).
* After the synchronous script finishes, the microtask queue runs, logging " Success " .
Execution order:
Start
End
Success
This matches option B .
JavaScript Knowledge References (text-only)
* Promise .then() callbacks execute after the current call stack finishes (microtask queue).
* Synchronous logs run immediately, before promise callbacks.
