4:54 with Guil Hernandez

This video covers one solution to the first part of the "Number Guessing Game" challenge.

Resources

while loop solution

Review how you might write the number guessing program using a while loop.

const main = document.querySelector('main');
const randomNumber = getRandomNumber(10);
let guess;

function getRandomNumber(upper) {...}

while ( parseInt(guess) !== randomNumber ) {
  guess = prompt('I am thinking of a number between 1 and 10. What is it?');
}

main.innerHTML = `<h1>You guessed the number! It was ${randomNumber}.</h1>`;

    The goal was to ask the user to guess the number from one to 10 again and 0:00
    again until their guests match the number assigned to the randomNumber variable. 0:00
    Now I'll show you my solution which you can compare to what you wrote. 0:05
    You can also reference all my code when you download the project files. 0:09
    I chose to use a do...while loop. 0:13
    So I'll start by adding a do while statement. 0:16
    Everything you add inside this do block is the loop itself, and 0:22
    it's going to run at least once. 0:27
    In the do block, I'll first collect the player's guess. 0:29
