Inventory JS Fundamentals

function inventory(arr) {
    let heroes = [];

    for (let line of arr) {
      let [heroName, heroLevel, itemsString] = line.split(' / ');
      let items = itemsString ? itemsString.split(', ') : [];

      let hero = {
        name: heroName,
        level: Number(heroLevel),
        items: items
      };

      heroes.push(hero);
    }

    heroes.sort((a, b) => a.level - b.level);

    for (let hero of heroes) {
      console.log(`Hero: ${hero.name}`);
      console.log(`level => ${hero.level}`);
      console.log(`items => ${hero.items.join(', ')}`);
    }
}

OR

function inventory(list) {
  let heroes = [];
  for (let line of list) {
    let [heroName, level, items] = line.split(' / ');
    let currentHero = {
      heroName,
      level: Number(level),
      items
    }
    heroes.push(currentHero);
  }
  heroes.sort((a, b) => a.level - b.level);
  heroes.forEach((currentHero) => {
    console.log(`Hero: ${currentHero.heroName}`);
    console.log(`level => ${currentHero.level}`);
    console.log(`items => ${currentHero.items}`);
  });
