The second solution is pretty clever and has less lines but it is harder to read and it is not as performant. you will notice that I am giving it an empty array just in case there is no last array or nothing is there the .reverse will error if it doesnt have at least an empty array so we are giving it an empty array if array doesnt have something to pop. It goes to show that the code is the crafted around the solution, not the other way around. Thanks for keeping DEV Community safe.
