Here the first `.then` shows `1` returns `new Promise(…)` in the line `(*)`. After one second it resolves, and the result (the argument of `resolve`, here it's `result*2`) is passed on to handler of the second `.then` in the line `(**)`. It shows `2` and does the same thing.
So the output is again 1 -> 2 > 4, but now with 1 second delay between `alert` calls.
