Matching two Values from an Array (CSV) and an Axios Request and if so.. print out proper value (third value)

hditano — Mon, 29 Jun 2020 08:37:24 +0000

I'm still learning Javascript. so this is what i came with. Which obviously its not working as expected.

const ESI = axios.get('https://esi.evetech.net/latest/markets/10000002/orders/?datasource=tranquility&order_type=all&page=1')
.then(function (response) {
  console.log(response.data);
  for(let i of response.data){
    console.log(i.type_id);
  }
}) 

function doStuff(data) {
  //Data is usable here
  console.log(data);
}

function parseData(url, callBack) {
  Papa.parse(url, {
      download: true,
      dynamicTyping: true,
      complete: function(results) { 
          callBack(results.data);
      }
  });
}

const csvData = parseData("invTypes.csv", doStuff);

console.log(csvData);

Array.prototype.diff = function(csvData) {
  var ret = [];
  this.sort();
  csvData.sort();
  for( var i = 0; i < this.length; i += 1) {
    if(csvData.indexOf(this[i] > -1) > -1) {
      ret.push(this[i]);
    }
  }
  return ret;
}

console.log(ESI.diff(csvData));

I am trying to do the following.
Axios returns the results in the following format.

0:
duration: 90
is_buy_order: false
issued: "2020-04-26T13:09:52Z"
location_id: 60003760
min_volume: 1
order_id: 5672796166
price: 99890
range: "region"
system_id: 30000142
type_id: 33092
volume_remain: 25
volume_total: 28

This is what i get from PapaParse (its around 35.000 csv lines parsed).

18941: Array(15)
0: 33092
1: 257
2: "Caldari Destroyer"
3: "Skill at operating Caldari destroyers."
4: "0E-10"
5: 0.01
6: "0E-10"
7: 1
8: 1
9: 100000
10: 1
11: 377
12: 33
13: "None"
14: 0

As you can see Type_ID and 0: Matches since they are both the same ID : 33092. If so..i need to return the value of the 2: which in this case is Caldari Destroyer.

Not quite sure what would be a better way to handle this?? MongoDB? MySql?
If so..what should i look for?

CSharp When to use properties

First at all, i started to learn C# a few days ago, at the moment i’m in the “Set/Get” Chapter. So every new thing that comes in my tutorial i try to apply it on my small application. Even tho if i do not understand the concepts i go the alternative places and look for suggestions, which is not this case.

I tought that maybe in the Class Calculator i could add a set and get so i do not have to declare the num1, num2 variables on each method? (Sumar, Restar, Division, Multiplicacion)

class Calculo
{

public static void Suma()
{

int num1, num2 = 0;
Console.Write(" Ingrese el primer numero que quiere sumar: ");
num1 = Convert.ToInt32(Console.ReadLine());
Console.Write(" Ingrese el segundo numero que quiere sumar: ");
num2 = Convert.ToInt32(Console.ReadLine());
Console.WriteLine(" Resultado es:   " + (num1 + num2));

}

public static void Resta()
{

int num1, num2 = 0;
Console.Write(" Ingrese el primer numero que quiere restar: ");
num1 = Convert.ToInt32(Console.ReadLine());
Console.Write(" Ingrese el segundo numero que quiere restar: ");
num2 = Convert.ToInt32(Console.ReadLine());
Console.WriteLine(" Resultado es: " + (num1 - num2));

}

public static void Division()
{

int num1, num2 = 0;
Console.Write(" Ingrese el primer numero que quiere Dividir: ");
num1 = Convert.ToInt32(Console.ReadLine());
Console.Write(" Ingrese el segundo numero que quiere Dividir: ");
num2 = Convert.ToInt32(Console.ReadLine());
Console.WriteLine(" Resultado es: " + (num1 / num2));

}

public static void Multiplicacion()
{

int num1, num2 = 0;
Console.Write(" Ingrese el primer numero que quiere multiplicar: ");
num1 = Convert.ToInt32(Console.ReadLine());
Console.Write(" Ingrese el segundo numero que quiere multiplicar: ");
num2 = Convert.ToInt32(Console.ReadLine());
Console.WriteLine(" Resultado es: " + (num1 * num2));

}
}
Thank you!

Learning C# Advice.

Hello everyone.
Due to the covid19 and the current lockdown in my country (Argentina) i finally took a further step and i'm currently learning C# (Mostly interested in BackEnd, Desktop Software and Games). Even tho i tried to start with tutorials from GameDev.tv about Unity, stopped half way and decided to get into the language itself before going to Unity (hope it was a good decision)
I took the free april trial from PluralSight and been working on the C# Path from the Website.
Even tho i'm almost finishing the Scott Allens course, which sometimes i get difficult to get into, usually go to alternative websites to get a better grasp like (https://www.tutlane.com/, https://www.tutorialspoint.com/, https://www.completecsharptutorial.com/).
My goal was to try to finish some little projects, like a calculator, which already did. I even tried a few codewars.com exercises which sometimes i found out difficult to follow along.
Do you have any other advice for a beginner on what kind of projects or what kind of path should i take on for a better understand of the fundamentals of a language?? I'm willing to pay for a learning site, something than doesn't go like crazy on price.

Regards

Hernan
