It will evaluate the first condition to true or false. If it is false it will pass to the else if() condition. Your second guess no matter what number you put in, 15 for example, will always evaluate to true and you win every time.
I think this is because the first nested if statement is saying the variable correctGuess is true, so it passes straight through to 'You guessed the number!' to end the program.

var correctGuess;
