Question how do i push a data to an array ?

[xLeeJYx]

With this code below i got [ ] in console. Not sure what i done wrong

function priceCheckCard(item) {

    var cardPrices = [];

    market.getItemPrice(item.appid, item.market_hash_name, (err, data) => {
        if (err) {
            console.log(err.message)
        } else {
            cardPrices.push(data.median_price)
        }
    })
    return cardPrices
}

You're pushing the data correctly, you just seem to not understand async. Calling market.getItemPrice is essentially requesting that it retrieve the item price and then let you know when it's finished. You then return immediately, without waiting for the callback.
