Question itemsToGive with multiple items

[Melonos]

When I do itemsToGive.market_name_hashname it only takes the first item in the trade.

what if I want for all of them? 

 

Please give an example. 

[Dr. McKay]

itemsToGive is an array.

It outputs this.

And I wanna get both names,
and but them into two variables.

 

CASE1 = CASE1 NAME

CASE2 =  CASE2 NAME

[Dr. McKay]

Do you know what an array is?

[adma]

If you want to get the market hash names of each item you're giving, you would probably use forEach or a for loop to cycle through the itemsToGive array ...
e.g

manager.on('newOffer', function(offer) {
	offer.itemsToGive.forEach(function(item) {
		console.log("Item to give : " + item.market_hash_name); // Items to give: Chroma 2 Case
	});
});

a for ... of loop (edited from for..in loop)

manager.on('newOffer', function(offer) {
	for (var item of offer.itemsToGive) {
		console.log("Items to give : " + item.market_hash_name); // Items to give: Chroma 2 Case
	}
});

a regular for loop

manager.on('newOffer', function(offer) {
	for (var i = 0; i < offer.itemsToGive.length; i++) {
		console.log("Items to give #" + i + " : " + offer.itemsToGive[i].market_hash_name); // Items to give #1 : Chroma 2 Case
	}
});

Same deal will apply for itemsToReceive ... or any other array you wanted to cycle through

[Dr. McKay]

It's not recommended to use for ... in on an array.

[adma]

Alright, cheers McKay. Updated my answer with a for..of loop instead.
