Full Stack JavaScript Techdegree Student 1,291 PointsWhat is the + sign next to the guess in the conditional statement? can someone clear this up for me? thank you!
let currentGuess = false; let realUn = prompt("guess a numbah between 1 -10 ? "); const answer = 6;
if (+realUn === answer ) { currentGuess = true alert("uuuu smart!!!") alert("you may enter")
}else { alert("go home dummy") }
/// I made some sample code just for a reference but I'm referring to the top line conditional statement///

Treehouse Guest TeacherHi Jordan Bester , when you see the addition operator used that way, it becomes a unary operator that attempts to convert a string containing numbers into an actual number type, similar to what the Number() method does.

The + beside the realUn (+realUn) converts the value of realUn to a numerical number first, then compares the converted number to answer value(6)

1,988 PointsHi dude. I noticed when you posted your code it looked like this:
let currentGuess = false; let realUn = prompt("guess a numbah between 1 -10 ? "); const answer = 6;
if (+realUn === answer ) { currentGuess = true alert("uuuu smart!!!") alert("you may enter")
}else { alert("go home dummy") }
Just a tip for future questions you might have, you can use three backticks and the word "javascript" (```javascript) like that at the beggining of your code and then another three at the end to close it. By doing this it will format your code to look like this:
Hope this was useful, even though you didnt ask lol
