The logic is almost the same as in this setTimeout example.
If you're new to the JS Promises, I suggest starting here:
- What is a JavaScript Promise and how it works
- How to create Promises in JS and handle Promise chains
Even though Promise.resolve() doesn’t have any explicit delay, the code inside of .then() is executed asynchronously and has a lower priority than the synchronous code.
So, the console.log('resolved') will be executed after the console.log('end').
ANSWER: the string end will be logged first, followed up by resolved.
