nodejs accessing a variable inside a callback method

Question

How can I access the variable inventory outside the callback? I would like to access it and return it.

loadInventory = function () {

var inventory = [];

offers.loadMyInventory({
    appId: 730,
    contextId: 2,
    tradableOnly: true

}, function (err, items) {
    items.forEach(function (item) {
        inventory.push({
            asset_id: item.id,
            market_name: item.market_name
        });
    });
    //Not accessible here
});
};

//Not accessible here is within the callback in the above, – Joe Nov 17 '16 at 10:14 — Joe, Nov 17 '16 at 10:14
Can you share working code so I can execute it ? – Dhaval Soni Nov 17 '16 at 10:14 — Dhaval Soni, Nov 17 '16 at 10:14

You need loadInventory to take a callback, that whatever calls it would pass:

loadInventory = function (callback) {

var inventory = [];

offers.loadMyInventory({
    appId: 730,
    contextId: 2,
    tradableOnly: true

}, function (err, items) {
    items.forEach(function (item) {
        inventory.push({
            asset_id: item.id,
            market_name: item.market_name
        });
    });
    callback(inventory);
});
}; 

loadInventory(function(inventory) {
  console.log(inventory);
});
