Is there a way to simultaneously check multiple arrays?

In the following code snippet, it checks for the existence of auctions[0]. If it exists, it retrieves the value and proceeds to the next number. If not, it moves on to the next number and repeats the process until it reaches number 30.

Is there a cleaner and less convoluted alternative to achieve this?

if (ahValue.auctions[0]){
    var itemName = ahValue.auctions[0].item_name
    var itemLore = ahValue.auctions[0].item_lore
    var itemTier = ahValue.auctions[0].tier
    var itemSeller = ahValue.auctions[0].auctioneer
    var itemBids = ahValue.auctions[0].bids.length
    console.log(`${itemName}${itemLore}${itemTier}${itemSeller}${itemBids}`)
}
// The process above repeats for indices 1 through 30

Answer №1

To iterate through the data, you can utilize a for loop:

for(let i = 0; i <= 30; i++) {
     if (ahValue.auctions[i]){
        var itemName = ahValue.auctions[i].item_name
        var itemLore = ahValue.auctions[i].item_lore
        var itemTier = ahValue.auctions[i].tier
        var itemSeller = ahValue.auctions[i].auctioneer
        var itemBids = ahValue.auctions[i].bids.length
            

        console.log(`${itemName}${itemLore}${itemTier}${itemSeller}${itemBids}`)
     }
}

Answer №2

Consider trying something along these lines.

auctions.length will give you the array's length, allowing for easy iteration through all elements.

This is the active code snippet.

var auctions = [];
auctions[0] = { "item_name" : "item_name1",  "item_lore" : "item_lore1", "tier" : "tier1",  "auctioneer" : "auctioneer1" , "bids":"bids1"};
auctions[1] = { "item_name" : "item_name2",  "item_lore" : "item_lore2", "tier" : "tier2",  "auctioneer" : "auctioneer2" , "bids":"bids2"};

for(var i = 0; i < auctions.length; i++){
 if(auctions[i]){
          console.log(auctions[i].item_name);
 }
}

Your complete code will resemble this:

for(let i = 0; i <= ahValue.auctions.length; i++) {
     if (ahValue.auctions[i]){
        var itemName = ahValue.auctions[i].item_name
        var itemLore = ahValue.auctions[i].item_lore
        var itemTier = ahValue.auctions[i].tier
        var itemSeller = ahValue.auctions[i].auctioneer
        var itemBids = ahValue.auctions[i].bids.length
            
         console.log(`${itemName}${itemLore}${itemTier}${itemSeller}${itemBids}`)
     }
}
