setTimeout doesn't run if there is loop defined before

Question

I have code like this:

function s() {console.log("in set time out")};

setTimeout(s, 100);
for (let i = 0; i < 50000; i++) {
 console.log(i);
};

This is output of console:

As you see the function s ran only after the loop ends.

Please explain me if you have experience with this problem.

Thank you.
