JavaScript JavaScript Basics (Retired) Making Decisions with Conditional Statements Improving the Random Number Guessing Game

I run this code through the console and it works. Anything wrong with this approach?

var correctGuess = false; var randomNumber = Math.floor(Math.random()*6)+1; var guess = prompt("Guess the number between 1 - 6");

if (parseInt(guess)===randomNumber) {correctGuess=true;} else if (parseInt(guess)<randomNumber) {prompt ("guess more");}

else if (parseInt(guess)>randomNumber) {prompt ("guess less");}

if (correctGuess) {document.write ("<p>Hurray</p>");} else {document.write ("<p>Not Hurray</p>");}

You're good through the first try, then it looks like the user is getting a second chance to guess but they aren't.

For the second guess to work correctly, you'll need to save the result of calling "prompt" back into the "guess" variable. Then, you'll need to test it one more time to see if it matches the "randomNumber".

Very interesting - I think I forgot that javascript console executes the code line after line - never parallelly

It's never "parallel", but it's also not always sequential. You'll see more on that when you get to "event handling".

Happy coding!
