True or False

Could someone please help me, my outcome is always showing "Sorry, the number was 6."

What am I doing wrong?

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

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

if (correctGuess) { console.log('You guessed the number!'); } else { console.log(Sorry. The number was ${number}.); }

If the answer matches, a new global variable "currectGuess" (with 2 "u"s) is created and set to true.
But the variable used to control the output is "correctGuess" (with an "o").

Also, a comparison with the type-sensitive operator "===" will never consider a string (as prompt gives) to match with a number. You could use the standard comparison "==" to allow the system to perform a conversion, or you could do it explicitly.

As mentioned in the video, another way to write this code would be to simply add a + in front of the variable guess in the conditional statement because you need to convert the string value returned by prompt to a number value in order to achieve your desired results. Ex: if ( +guess === number ) { correctGuess = true; }

Also, your last line of code should include a template literal Ex: else { console.log(Sorry. The number was ${number}.); }
