Tell us what’s happening:

Question 17(displayResults) is formatted correctly but is not verifying that it’s correct

Your code so far

const poll = new Map()
function addOption(option){
  if (poll.has(option)){
 return `Option "${option}" already exists.`} else if (!option || "") {
    return `Option cannot be empty.`
  } else {
    const voters = new Set();
    poll.set(option, voters)
 return `Option "${option}" added to the poll.`
  }
}
console.log(addOption('e'))
console.log(addOption('e'))
console.log(addOption())
function vote(option, voterId){
  const voters = poll.get(option)
if (!poll.has(option)){
  return `Option "${option}" does not exist.`
} else if (voters.has(voterId)){
  return `Voter ${voterId} has already voted for "${option}".`
} else {
  
  voters.add(voterId)
  return `Voter ${voterId} voted for "${option}".`
}
}
console.log(vote('e', '2'))
console.log(vote("e", '5'))

function displayResults(){
let resultString = `Poll Results:\n`
for (const [option, voters] of poll.entries()){resultString += `${option}: ${voters.size} votes\n` }
  return resultString
}

addOption('3')
addOption('4')
vote('3', '4')
vote('4', '3')
console.log(displayResults())
