opskins (highest price for item)

[pekinese]

I tried to get the highest price of today for an array of items.

My code until now:

      opskins.getPriceList(730, function(err, prices) {
        if (err)
          console.log("error!");
        if(prices){
          highest_price = Infinity;
          for (var item in prices) {
              if(keys.includes(item)){
                //how to continue now?
              }
          }
        }
      });

Any suggestions how to get only the "latest" price for each item, so I can compare and get the highest price of ALL items for only today? In the end I only need to get one value, for example for this JSON object:

 

"item1": {
"2017-07-17": {"price": 800},
"2016-07-16": {"price": 453},
"2016-07-15": {"price": 435}
},
"item2": {
"2017-07-17": {"price": 622},
"2016-07-16": {"price": 643},
"2016-07-15": {"price": 593}

}

 

It would return 800.

I need to get the highest price See post above.

Getting the highest price would be pointless; you'd basically always just get $99,999.99.

See the example above. In this case I would need to get 800.

You'd want to foreach loop over the object and pull the maximum value, just like you're foreach looping prices to get the item.

But how to get the date which is the "key", I would need to get only the first entry of each price "array". How to do so, any way without using the date, because as I've seen the first date isn't always the "current" date, isn't it?

[Dr. McKay]

If you only want the latest, you could get the keys using Object.keys, sort it (YYYY-MM-DD sorts alphabetically quite nicely), then pull the first/last element (depending on how you sorted it).
