Analyzing the components within an object

Analyzing the components within an object

Currently, I am developing a web scraper that stores results in a JSON format similar to the following:

{"Products" : [
   {"Title":"Voice Recorder ISD1932","Results": [
      {"Stock":1,"Price":11.4,"Date":"18-8-2014:3:36"},
      {"Stock":1,"Price":12.4,"Date":"18-8-2014:3:38"},
      {"Stock":1,"Price":12.4,"Date":"19-8-2014:0:40"},
      {"Stock":1,"Price":12.4,"Date":"19-8-2014:21:46"},
      {"Stock":1,"Price":12.4,"Date":"21-8-2014:22:4"},
      {"Stock":1,"Price":12.4,"Date":"22-8-2014:0:40"},
      {"Stock":1,"Price":12.4,"Date":"23-8-2014:0:48"},
      {"Stock":1,"Price":12.4,"Date":"23-8-2014:13:56"},
      {"Stock":1,"Price":12.4,"Date":"23-8-2014:13:56"},
      {"Stock":1,"Price":12.4,"Date":"23-8-2014:13:56"},
      {"Stock":1,"Price":12.4,"Date":"23-8-2014:13:56"}, 
      {"Stock":1,"Price":12.4,"Date":"23-8-2014:13:56"},
      {"Stock":1,"Price":12.4,"Date":"23-8-2014:13:56"}],
    "id":"4a1e90d7-e578-4bd5-b888-38c7bbfb4af5"}]}

For example, the first element in the results would be:

{"Stock":1,"Price":11.4,"Date":"18-8-2014:3:36"}

The second would be:

{"Stock":1,"Price":12.4,"Date":"18-8-2014:3:38"}

And so on.

Each time I scrape the website, it adds a new element.

I am looking to implement a cleaner function that removes an element if both stock and price are equal to the previous one, excluding the date information.

Using this example, if the third element is identical to the second, I want to remove it. The same goes for subsequent elements.

If you want to achieve this task effortlessly, utilize the array.filter method:

let data = ...;

for(let i = 0 ; i < data.Products.length ; i++) {
    let product = data.Products[i];
    product.Items = product.Items.filter(function(item, index, array) {
        return index == 0 || !(item.Quantity === array[index - 1].Quantity && item.Price === array[index - 1].Price);
    });
}

Here's a method to iterate through objects and remove duplicates based on a specified criterion:

var arr = {"Products" : [
   {"Title":"Voice Recorder ISD1932","Results": [
      {"Stock":1,"Price":11.4,"Date":"18-8-2014:3:36"},
      {"Stock":1,"Price":12.4,"Date":"18-8-2014:3:38"},
      {"Stock":1,"Price":12.4,"Date":"19-8-2014:0:40"},
      {"Stock":1,"Price":12.4,"Date":"19-8-2014:21:46"},
      {"Stock":1,"Price":12.4,"Date":"21-8-2014:22:4"},
      {"Stock":1,"Price":12.4,"Date":"22-8-2014:0:40"},
      {"Stock":1,"Price":12.4,"Date":"23-8-2014:0:48"},
      {"Stock":1,"Price":12.4,"Date":"23-8-2014:13:56"}, 
      {"Stock":1,"Price":12.4,"Date":"23-8-2014:13:56"}
    ],
    "id":"4a1e90d7-e578-4bd5-b888-38c7bbfb4af5"}]};

var data = arr.Products[0].Results;

for(var i = 0; i != data.length; i++) {
    var stock = data[i].Stock;
    var price = data[i].Price;
    var date = data[i].Date;
    if( i < data.length - 1 && date === data[i + 1].Date) {
        data.splice(i + 1,1);
        i--;
    }
}

Here is the code snippet in JavaScript:

var data = { "output": {} };
var outputData = {};
var temporaryArray = [];
for(var i = 0; i < 10; i++){
    var stockValue = i + 20;
    var priceValue = "14." + (i + 10);
    var fetchValue = '12' + i;
    outputData = {'stock': stockValue, 'price': priceValue, 'fetch': fetchValue};
    if(i == 0) {
        temporaryArray.push(outputData);
    } else {
        var lastObject = temporaryArray[temporaryArray.length - 1];
        if(lastObject.stock == stockValue && lastObject.price == priceValue){
            console.log("Match found"); // If a match is found, do not add
        } else {
            temporaryArray.push(outputData);
        }
    }
}
data.output = temporaryArray;
JSON.stringify(data);
