Do we need to create the guessLess variable? Can't we just use the previous guessMore variable instead?

I was wondering why we create the guessLess variable inside the second else if statement, when we already have created a new variable called guessMore inside the first else if statement? Can't we use the guessMore variable for both else if statements? And tweak the prompt question for the user input. Even the name sounds pretty logic with the "More" word since we want the player to guess "more".

Hi. You have to create a new variable to each user try. Why u have to do it? as u saw in the video each time the user gets a prompt dialog and he the input he send being stored inside a variable in order to make some conditional checks.

so for try number one, lets say the user enters the wrong random number, this value being assigned to the "guessMore" variable and he is being stored there.

in the second attempt You have to create another variable in this case "guessLess" in order to store the second random number the user has been guessed.

You can't store 2 values inside a variable, unless it's an array, nevertheless for each attempt u need to perform some conditional checks, and for each attempt u need to have a variable that stores the input from the user.

hope this helps
