Guessing Game 1 - 100, Javascript

console.log('Guess a number from 1 to 100 or type "Cheat" to find the answer');
var answer = Math.floor((Math.random() * 100) + 1);
var i = 1;
//var c = 1;

function guessNum(answer){
    var min = 0;
	var max = 100;
    var mid;
    
     while (mid != answer){
        mid = Math.floor((max + min)/2);
        //console.log(mid);
        if(mid === answer){
            //console.log(c);
            console.log(mid);   
        }
        else if (mid < answer){
            min = mid;
            
        }
        else {
            max = mid;   
        }
//        c++;
    }

while (guess != answer){
    var guess = prompt();
    
    if (guess > 100){
        console.log("Error, Cannot be bigger than 100");
    }
    else if (guess < 0){
        console.log("Error, Cannot be smaller than 0");
    }
    else if (guess == answer){
        console.log("You are correct, the answer is " + answer);
        console.log("It took you " + i +" tries");
    }
    else if (guess < answer){
        console.log("too low");
    }
    else if (guess > answer){
        console.log("too high");
    }
    else if (guess == "Cheat"){
        guessNum(answer);
