How do I run every exported function - node.js

Question

So i have this mess of a js file
cardPool = []
class Card {
constructor(name = "", portrait = "", bloodCost = 0, boneCost = 0, power = 0, health = 1, sigilList = ["No sigil"]) {
this.name = name
this.portrait = portrait;
this.bloodCost = bloodCost;
this.boneCost = boneCost;
this.power = power;
this.health = health;
this.sigilList = sigilList;
cardPool.push(this)
}
Damage(dmg = 1) {
this.health -= dmg
}
}
blank = new Card("blank", "🔳");
income = new Card("income", "⬇️");
module.exports = {
Card,
blank,
income,
bear: function () { new Card("Grizzly", "🐻", 3, 0, 4, 6) },
wolf: function () { new Card("Wolf", "🐺", 2, 0, 3, 2) },
cardPool,
};
All I want to do is on start up it run all of the function being exported. There more function that I export but here only a few so stack overflow won't scream at me. This is for a game that I'm making to be able to handle multiple instance of the same card. You can read about why I make new card using function here: How to change a local class varible node js . And I need a card pool so that I can do stuff in another file here my other question: How can i put an object inside a list on Initialization. Now I need on startup put all the card that I make in the module.export in the cardPool.

The best way to do this would be placing the functions in some kind of container (for example an array or a map) (in case you later want to export other functions from the file that don't create cards). Here's the simplest way with an array:
// Note the return statements! The functions will not return anything without them!
function bear () { return new Card("Grizzly", "🐻", 3, 0, 4, 6) }
function wolf () { return new Card("Wolf", "🐺", 2, 0, 3, 2) }
module.exports = {
// ...
cardCreatorFunctions: [bear, wolf, /* and maybe others */],
}
Then, you can iterate through the array and push created cards into cardPool one-by-one:
for (let fun of cardLib.cardCreatorFunctions) {
cardLib.cardPool.push(fun())
}
Or you can do it in one statement:
cardLib.cardPool = cardLib.cardCreatorFunctions.map(fun => fun())
