Question

In the era of heroes, every hero has his own items which make him unique. Create a function which creates a register for the heroes, with their names, level, and items, if they have such. The register should accept data in a specified format, and return it presented in a specified format.

The input comes as array of strings. Each element holds data for a hero, in the following format:
“{heroName} / {heroLevel} / {item1}, {item2}, {item3}...”

You must store the data about every hero. The name is a string, the level is a number and the items are all strings.

Examples:

Input:
Isacc / 25 / Apple, GravityGun
Derek / 12 / BarrelVest, DestructionSword
Hes / 1 / Desolator, Sentinel, Antara

Output:
[{"name":"Isacc","level":25,"items":["Apple","GravityGun"]},{"name":"Derek","level":12,"items":["BarrelVest","DestructionSword"]},{"name":"Hes","level":1,"items":["Desolator","Sentinel","Antara"]}]

Input:
Jake / 1000 / Gauss, HolidayGrenade

Output:
[{"name":"Jake","level":1000,"items":["Gauss","HolidayGrenade"]}]

---

The output is a JSON representation of the data for all the heroes you’ve stored. The data must be an array of all the heroes. Check the examples above for more info.

Answer 1

Here is my solution:

function heroicInventory(dataRows) {

    let heroData = [];
    for (let i = 0; i < dataRows.length; i++) {
        let currentHeroEl = dataRows[i].split(" / ");

        let currentHeroName = currentHeroEl[0];
        let currentHeroLevel = Number(currentHeroEl[1]);

        let currentHeroItems = [];
        if (currentHeroEl.length > 2) {
            currentHeroItems = currentHeroEl[2].split(", ");
        }

        let hero = {
            name: currentHeroName,
            level: currentHeroLevel,
            items: currentHeroItems
        };
        heroData.push(hero);
    }
    console.log(JSON.stringify(heroData));
}

heroicInventory([
    "Isacc / 25 / Apple, GravityGun",
    "Derek / 12 / BarrelVest, DestructionSword",
    "Hes / 1 / Desolator, Sentinel, Antara"
]);
