Create a multiple object with dynamic names

Question

I created a function which allows to return an object whose name change to each loop.

I done this function like this :

function createObjPack(index){
    var currentPack = packVehicule[key].libelle;

    return [eval(currentPack + ' = {}' ), calcul(currentPack, key)];
};

The variable curentPack contains the name of the current object. The return must generate a object which name match the value of currentPack

I thought read the currentPack directly into an eval() function for change dynamicly the name but, it doesn't work.

Someone can help me ?

I think the parameter index should be named key shouldn't it? — Praind

Dnamic variable names seems like the wrong thing. Use an object whose keys are the dynamic names. And you don't need to use eval to create dynamic variable names, just assign window[currentPack], since all global variables are properties of window. — Barmar

Don't use dynamic variable names, use an object.

var packs = {}

function createObjPack(index) {
    var currentPack = packvehicule[index].libelle;
    var newPack = {};
    packs[currentPack] = newPack;
    return [newPack, calcul(currentPack, index)];
}
