Tell us what’s happening:

I am having trouble with step 29 of building a lunch picker. I do not recall how to display the output of the lunches array in a specific order other than logging just the array to console. My showlunchmenu function is not doing what its supposed to.

Your code so far

let lunches = [];

const addLunchToEnd = (arr, str) => {
  arr.push(str);
  console.log(`${str} added to the end of the lunch menu.`);
  return arr;
}

const addLunchToStart = (arr, str) => {
  arr.unshift(str);
  console.log(`${str} added to the start of the lunch menu.`);
  return arr;
}

const removeLastLunch = (arr) => {
  if (arr.length === 0) {
    console.log("No lunches to remove.");
    return arr;
  }
  let item = arr.pop();
  console.log(`${item} removed from the end of the lunch menu.`);
  return arr;
}

const removeFirstLunch = (arr) => {
  if (arr.length === 0) {
    console.log("No lunches to remove.");
    return arr;
  } else {
    let item = arr.shift();
    console.log(`${item} removed from the start of the lunch menu.`);
    return arr;
  }
}

const getRandomLunch = (arr) => {
  if (arr.length === 0) {
    console.log("No lunches available.");
    return arr;
  } else {
  let randomIndex = Math.round(Math.random() * (arr.length - 0) + 0);
  let lunch = arr[randomIndex];
  console.log(`Randomly selected lunch: ${lunch}`);
  return lunch;
  }
}

const showLunchMenu = (arr) => {
  if (arr.length > 0) {
    let [first, second, third] = arr;
    console.log(`Menu items: ${first}, ${second}, ${third}`)
  }
  else {
    console.log("The menu is empty.")
  }
}

Welcome to the forum :wave:

Did you test it? What does your function output to the console?

  1. showLunchMenu([“Pizza”, “Burger”, “Fries”, “Salad”]) should log “Menu items: Pizza, Burger, Fries, Salad” to the console.
