Code is not working. Can't figure out why. Browser giving me an error msg.

This is my code:

let correctGuess = false;
const number = 6;
const guess = prompt("Guess a number between 1 and 10.");

if (+guess === number) {
  correctGuess = true;
}

if (correctGuess === true) {
  console.log("You guessed the number!");
} else {
  console.log(`Sorry, the number was ${number}.`);
}

Good job, you are showing some good instincts at programming JavaScript!

Remember: when making the comparison of guess and number, guess is a string and number is an integer. You can make this work using a less strict == operator rather than the strict === operator.

Also remember to use back-tick quote marks in your else section for it to be syntactically correct.

Other than that, it looks great!

let correctGuess = false;
const number = 6;

const guess = prompt("Guess a number between 1 and 10.");

if (guess == number) {
    correctGuess = true;
 }

if (correctGuess === true) {
    console.log("You guessed the number!");
} else { 
    console.log(`Sorry, the number was ${number}.`); 
}
