Adding a count to a number guessing game

So i have a basic number guessing game and it works fine, however I would like someone to show me how i could display the number of attempted guesses at the end of the game. Also would it be possible to show previous guesses at the end of the game like this? enter image description here

var canvas;
canvas = openGraphics();
var max;
max = 100;
var numberToGuess;
numberToGuess =  50; // will be changed to Math.floor( Math.random() * max ) + 1;
canvas.setFont("comic sans ms", "15px", Font.Bold);
canvas.drawString("Number Guessing Game!");
var guess;
guess = prompt( "Please input your guess 1-100" );


do {
// check previous guess and alert low/high message
if ( guess ) {
    if ( guess > numberToGuess ) {
        alert( "Your guess was too high: " + guess);
    }
    else if ( guess < numberToGuess ) {
        alert( "Your guess was too low: " + guess);
    }
}

guess = prompt( "Please input your guess 1-100" );
} while ( guess != numberToGuess );

alert( "You guessed correctly! " + guess );
canvas.paint();

Sure, just keep a running track of the guesses. You should consider storing the actual input along with an indicator of whether it was high or low.

Start by declaring an empty array before the main loop

var guesses = [];

After the user has made a guess, add a new item to the list wiith the value, and whether it was high or low

if ( guess > numberToGuess ) {
    alert( "Your guess was too high: " + guess);
    guesses.push({value:guess,direction:'HIGH'});
}
else if ( guess < numberToGuess ) {
    alert( "Your guess was too low: " + guess);
    guesses.push({value:guess,direction:'LOW'});
}

Then at the end you can do 2 things

  1. The number of guesses before correctly guessing the answer will be guesses.length
  2. Enumerate guesses to output what each incremental guess was

So perhaps something along the lines of

canvas.drawString( "You guessed correctly! " + guess + " in " + guesses.length + " guesses");
for(var i=0;i<guesses.length;i++){
    canvas.drawString("Guess #" + (i+1) + ": " + guesses[i].value + " was " + guesses[i].direction);
}
