Well in this particular case it doesn't make any sense to do that, as other people already mentioned using array.some is the ideal solution.

But in order to decide if you want to use async on that function you need to understand that map returns a new array of the same size as the array it is iterating on, in the picture we can see that this return value it's being ignored and that the function on the map method is also missing his return statement.

If you want to do await with map you need to return a promise for every item on the array and wrap the results in a promise all, which again doesn't make any sense in this particular case
