We want you to write a function, organizeItems, that organizes items by category. The argument to the function is an array of item objects. Each item object has 3 properties, category (string), itemName (string), and onSale (Boolean). Here's an example: var itemData = [
{ category: 'fruit', itemName: 'apple', onSale: false },
{ category: 'canned', itemName: 'beans', onSale: false },
{ category: 'canned', itemName: 'corn', onSale: true },
{ category: 'frozen', itemName: 'pizza', onSale: false },
{ category: 'fruit', itemName: 'melon', onSale: true },
{ category: 'canned', itemName: 'soup', onSale: false },
];
The return value should be an object with category properties. Each property value is an array of items that belong to that category.
Here's an example return object based on our example input:
{
fruit: ['apple', 'melon($)'],
canned: ['beans', 'corn($)', 'soup'],
frozen: ['pizza']
};
Note that items having onSale set to true should have '($)' appended to their item name.

Following are the code to the given question:

function organizeItems(items) //defining a method organizeItems that takes an items in parameter

{

   var result = {};//defining an array as a result

   for(item of items) //defining for loop to count items value

{

          if(!(item.category in result))// use if to check category exists in dictionary

{

           result[item.category] = []; //use result to assign value in blank list         }                  

var name = item.itemName;   //defining variable that holds itemName value

       if(item.onSale)//use if to check item value

{

           name += '($)';//use name to add string value

       }

       result[item.category].push(name);    //use result to hold value

   }  

   return result;//return result value

}
