I have tried to pass the entire collection, and if it saves the value, as an array (logical), but what I want is that it only saves the newField and secondField fields with their respective values ​​in the old_user collection of the new_user collection, but I save them as null, this is the code:

db.getCollection("old_user").find()
  .forEach((elm) => {

    let elmId = elm.id

    let new_user = db.getCollection("new_user").find( {id : elmId}).toArray()

      if(new_user) {
        db.getCollection("old_user").updateOne({id: elmId}, {$set: {newfield: new_user.newField, secondfield: new_user.secondField}})
      }
  })

As far as I know, to access an object inside an array it is with the point annotation, if I make a query of the entire collection it returns it to me but if I do a console.log of new_user.newField it returns it to me as null

I appreciate any help!

I manage to capture the 0 that belongs to the total and I get both products in the subtotals tag to do the calculation, for example, if I buy 2 products for 25 it shows me 50, but I want both products and when I press the button it shows me the total in Total box.

For this, I am using the function calculAllbut I am not able to get said value.

Here I paste the js where I only need to obtain the sum of the total of the products. No matter how hard I try, I can't find the key, is it because I have to do two different subtotals? i.e. from each of the subtotals, store the value and then add it?

I want it to do the sum when I click on the event that it creates in the function createProduct, once I click it shows me the subtotals of the products but it does not make the total sum.

function updateSubtotal(product) {
     
    const price = product.querySelector('.price span')
    const priceElement = parseFloat(price.innerText)
     
    const quantity = product.querySelector('.i').value
    let quantityElement = quantity
     
    let subtotal = product.querySelector('.subtotal span')
    subtotal.innerText = priceElement * quantityElement
    console.log(subtotal)
}


function calculateAll(subtotal) {

    const firstProduct = document.querySelector('.rubber')   
    const secondProduct = document.querySelector('.beach')

    updateSubtotal(firstProduct)   updateSubtotal(secondProduct)

    let subTotalPrice = document.querySelectorAll('.subtotal span')

    subTotalPrice.forEach((i) => {
    let allSubTotalPrice = subTotalPrice[i]
    let totalPrice = document.querySelector('.total-value span')
    totalPrice.innerText = allSubTotalPrice

    function createProduct() {
        
    }
 
    window.addEventListener('load', () => {
    const calculatePricesBtn = 
    document.getElementById('calculate')
    calculatePricesBtn.addEventListener('click', calculateAll)
 
    const removeElement = document.getElementById('remove')
    removeElement.addEventListener('click', removeProduct)
 
    })

</body>

</html>

Only if I apply the margin:0and padding:0to all the css it removes the spaces, that is, I have to apply it to the li, all the h, the p, etc... So I don't know why it doesn't do it since I am applying it to all the html and body, it does not remove the margin. Any ideas?

I want the empty object filteredProducts{}to return tech and food as key but it returns empty, and I don't know where the error is.

function sortProducts(matrix) {
  //declaro las variables
  const filteredProducts = {};
  let techArray = [];
  let foodArray = [];
  //bucle para recorrer el array input
  for (let i = 0; i < matrix.length; i++) {
    let products = matrix[i];
    //declaro las variables para asignarle los nuevos valores
    let category = products.product;
    let tech = category === "tech";
    //condicional que agrega el valor tech al array 
    if (tech) {
      techArray.push(products[i]);
      filteredProducts.tech = techArray;
    }
  }
  //bucle para recorrer el array input
  for (let i = 0; i < matrix.length; i++) {
    let products = matrix[i];
    //declaro las variables para asignarle los nuevos valores
    let category = products.product;
    let food = category === "food";
    //condicional que agrega el valor tech al array 
    if (food) {
      foodArray.push(products[i]);
      filteredProducts.food = foodArray;

    }
  }
  //retorno los valores en el array vacio
  return filteredProducts;
}

//este es el array de input

let matrix = [
  [{
    product: "MacBook",
    price: 1019,
    category: 'tech'
  },
   {
     product: "Cheerios",
     price: 5,
     category: 'food'
   },
  ],

  [{
    product: "Snickers",
    price: 1.5,
    category: 'food'
  },
   {
     product: "Air Pods",
     price: 129,
     category: 'tech'
   },

I am doing a query to a sqlite database so that it returns the trackid, song and duration but they ask me for the duration to be short, medium or long depending on the number, I can get the trackid, the songs and the durations but I do not get that the duration field which is an int is displayed as a text string

I am executing the following query:

SELECT TrackId, Name as [cancion], Milliseconds as [duracion] FROM tracks;

And it gives me this: enter image description here

I try to use select cast(Milliseconds as text) from tracks;but it returns empty

Any ideas??

Thanks in advance
