Tell us what’s happening:

I am having trouble with tests #12 & #13 … so far

Both relate to the removeLastLunch function - i’m logging the results as i go and they appear to be correct

Your code so far

let lunches = [];

function addLunchToEnd(arr, str) {
  lunches = [...arr];
  lunches.push(str);
  console.log(str + " added to the end of the lunch menu.");
  return lunches;
}




function addLunchToStart(arr, str) {
  lunches = [...arr];
  lunches.unshift(str);
  console.log(str + " added to the start of the lunch menu.");
  return lunches;
}



function removeLastLunch(arr) {
  lunches = [...arr];
  console.log(lunches);
  const removeLast = lunches.pop();
  console.log(lunches);
  console.log(removeLast);
  console.log(lunches.length);
  if (lunches.length === 0) {
    console.log("No lunches to remove.")
    
  } else {console.log(removeLast + " removed from the end of the lunch menu.")}
  
  return lunches;
}

removeLastLunch(["Stew", "Soup", "Toast"])


function removeFirstLunch(arr) {
  const removeFirst = lunches.shift();
  if (removeFirst > 0) {
    console.log(removeFirst + " removed from the start of the lunch menu.")
  } else {console.log("No lunches to remove.")}
  return lunches;
}



function getRandomLunch(arr) {
  const randomElement = lunches[Math.floor(Math.random() * lunches.length)];
  if (randomElement > 0) {
    console.log("Randomly selected lunch: " + randomElement)
  } else {console.log("No lunches available.")}
  return lunches;
}



function showLunchMenu(arr) {
  const [...rest] = lunches
  if (lunches > 0) {
    console.log("Menu items: " + rest)
  } else {console.log("The menu is empty.")}
}

results of my console.logs:

[ 'Stew', 'Soup', 'Toast' ]
[ 'Stew', 'Soup' ]
Toast

Toast removed from the end of the lunch menu.

Think about the order in which you are doing things in this function.

4
  1. copying from arr to lunches
  2. removing the last element
  3. then logging the appropriate string

isn’t that the correct order?

5

Give that some more thought, please.

7

ive tried removing the element first, then copying what is left to “lunches” - still doesn’t work.

both ways seem to correct to me anyway

8

What happens if you pass in an empty array?

9

are you asked to leave the passed in array unchanged or to change it?
