Not getting the Wrong and right answers

let questions = [ ['How many Stars on the flag', 50], ['How many championships has the lakers won?', 10], ['How many terms can a president serve', 2] ] let answers = 0 let question let guess let html = '' let correctAnswers

function print(messages){ document.write(messages)

}

function trivia() { for(let i = 0; i < questions.length; i ++) { question = questions[i][0] answers = questions[i][1] guess = prompt(questions[i][0]) if (guess === answers){ correctAnswers += 1 } else if (guess !== answers) { correctAnswers == 0 } } }

trivia() html = You got this ${answers} correct alert(html)

You are missing ;]] after correctAnswers. There is an error or errors on your function trivia() line, but I cannot find it. Sorry, I am of limited help.

For future questions, use Markdown formatting to preserve the appearance of the code, or share the entire workspace by making a snapshot and posting the link to it.

But assuming no errors are being concealed by the lack of formatting, this code seems to run properly. But some things I noticed:

  • a "print" function is defined to output to the page but it is never used
  • only the correct count is shown in an alert message
  • there is no code here that would identify which specific questions were right (or wrong)
  • the "else if" could be a plain "else" since it only tests for the opposite of the "if"
  • the code in the "else if" body is doing a comparison instead of an assignment
  • replacing the comparison with an assignment is probably not desirable as it would zero out the score

let questions = [
    ['What does the F in FBI stand for?', 'federal'],
    ['In which country is a K2 present?', 'pakistan'],
    ['What NFL Quarterback has been to the most superbowls?', 'tom brady'],
    ['What is the name of the bear in Jungle Book?', 'baloo'],
    ['On a farm a what animal is called a kid ?', 'goat']
]
// I declare some variables
let userGuess 
let wrongAnswer = 0
let rightAnswer = 0
let question
let html  
let answers
// Created a function 
function print(message) {
    document.write(message)
}
// I created a for loop to iterate through the array
    for (let i = 0; i < questions.length; i += 1) {
        question = questions[i][0]
        answers = questions[i][1]
        userGuess = prompt(questions[i][0])
        if (userGuess.toLowerCase() === answers) {
            rightAnswer += 1
        } else {
            wrongAnswer += 1
        }


    }

    if(rightAnswer > 2) {
        alert('Good stuff bro ')
    } else {
        alert('You need more practice')
    }


html = `You got this many ${rightAnswer} right, and you got this many ${wrongAnswer} wrong. `
print(html)

So I went back and fixed some things, if there are any more suggestions I would love to hear them so that I can improve
