Add a variable to an existing array

Question

Add a variable to an existing array

As a beginner in the world of programming, I usually rely on online resources to solve my coding problems. However, this time I'm facing an issue that I can't find the solution to online. I have been trying to push a variable into an array and then checking if it actually made it into the array by using console.log. But instead of seeing the names of the variables I pushed in like "card_Fireball" or "card_Waterbolt", all I see is [Card, Card]. The code snippet I am working with is as follows:

var Deck = [];

function Card(name, type, cost, points, damage, heal){
    this.name = name;
    this.type = type;
    this.cost = cost;
    this.points = points;
    this.damage = damage;
    this.heal = heal;
}

var card_Fireball = new Card("Fireball", "spell", 2, 1, 3, 0);
var card_Waterbolt = new Card("Waterbolt", "spell", 2, 1, 3, 0);

Deck.push(card_Fireball);
Deck.push(card_Waterbolt);

console.log(Deck);

While I believe the solution to this problem might be simple, my lack of experience as a beginner programmer is making it hard for me to figure out. Any help would be greatly appreciated! Thank you so much!

Answer №1

All your actions are on point, simply switch out the console.log with this:

console.log(JSON.stringify(Deck));

Answer 2

All your actions are on point, simply switch out the console.log with this:

console.log(JSON.stringify(Deck));

Answer 3

Answer №2

To access the names of the cards, simply use "Deck[x].name", where x represents the index of the card within the Deck array.

If you want to retrieve all the card names:

for(i=0;i<Deck.length;i++){
    console.log(Deck[i].name);
}

If your cards are named in a similar way as shown in the example, you can also retrieve variable names using this code snippet:

for(i=0;i<Deck.length;i++){
    console.log('card_' + Deck[i].name);
}

If you are looking to retrieve an array of the variable names that have been used, they may be lost along the way.
To collect an array of the names or any other property, consider creating a new array and adding each value to it.

var variables = [];
Deck.map(function(item) { variables.push(item.name) })
console.log(variables);

Output:

["Spark", "Ice Shard"]
