Tell us what’s happening:

I cannot pass test 24 no matter what I do even though it has the correct output.

Your code so far

const lunches = []
function addLunchToEnd(arr, str) {
  arr.push(str)
  console.log(`${str} added to the end of the lunch menu.`)
  return arr
}
function addLunchToStart(arr, str) {
  arr.unshift(str)
  console.log(`${str} added to the start of the lunch menu.`)
  return arr
}
function removeLastLunch(arr) {
  const arrayLength = arr.length
  const itemNum = arrayLength - 1
  const itemRemoved = arr[itemNum]
  arr.pop()
  if (arrayLength == 0) {
    console.log("No lunches to remove.")
  } else {
    console.log(`${itemRemoved} removed from the end of the lunch menu.`)
  }
  return arr
}
function removeFirstLunch(arr) {
  const arrayLength = arr.length
  const itemRemoved = arr[0]
  arr.shift()
  if (arrayLength == 0) {
    console.log("No lunches to remove.")
  } else {
    console.log(`${itemRemoved} removed from the start of the lunch menu.`)
  }
  return arr
}
function getRandomLunch(arr) {
  const arrayLength = arr.length
  const min = 1
  const max = arrayLength
  const num = Math.floor(Math.random() * (max-min) + min)
  if (arrayLength == 0) {
    console.log("No lunches available.")
  } else {
    console.log("Randomly selected lunch: " + arr[num])
  }
}
function showLunchMenu(arr) {
  const arrayLength = arr.length
  const start = arr.length - 1
  const lunch1 = arr[start - 3]
  const lunch2 = arr[start - 2]
  const lunch3 = arr[start - 1]
  const lunch4 = arr[start]
  if (arrayLength == 0) {
    console.log("The menu is empty.")
  } else if (lunch1 == undefined) {
    console.log(`Menu items: ${lunch2}, ${lunch3}, ${lunch4}`)
  } else {
    console.log(`Menu items: ${lunch1}, ${lunch2}, ${lunch3}, ${lunch4}`)
  }
}
console.log(getRandomLunch(["Pizza", "Fries", "Salad"]))

You are using the random num variable to access an element in arr, right? What is the first index in an array? How does that compare to the value of min?

Also, please do not create duplicate topics for the same issue. I will remove your duplicate post.
