@Titus If the input is 1 the for loop will do n%--i once : 1%0 returns NaN and stops the loop. When alert is called i is already equal to 0 so 1==i returns false.

should add n>1 to the final condition though, if You don´t want 1 to be prime.

Great answer! The &&i doesn't actually do anything in this program, so you can remove it.
