What is the best way to retrieve user information using an array?

Question

What is the best way to retrieve user information using an array?

Seeking assistance on code. I have two arrays: one containing product IDs and the other with full product details. My goal is to log products based on the product ID array by searching the product details array. If a match is found, the entire product details will be printed. Below are the two arrays:

var product_id = [
  {
    "order_id": "281774",
    "product_id": "203751",

  },
  {
    "order_id": "281774",
    "product_id": "198999",

  },
  {
    "order_id": "281774",
    "product_id": "199291",

  },

  {
    "order_id": "281774",
    "product_id": "256156",

  }
];

Second Array

var product_details = [
  {
    "id": "219",
    "product_id": "198999",
    "sku": "20148089",
    "prod_name": "Chocolate Mousse 1L",

    "price": "39.99"
  },
  {
    "id": "220",
    "product_id": "199291",
    "sku": "20008307",
    "prod_name": "Medium Carrots 500g",

    "price": "9.99"
  },
  {
    "id": "221",
    "product_id": "204759",
    "sku": "6009207908908",
    "prod_name": "Fresh Spicy Lentil & Vegetable Soup 600g",
    "price": "39.59"
  },
  {
    "id": "222",
    "product_id": "199015",
    "sku": "6009182131643",
    "prod_name": "Bulk Gouda Cheese 900g",
    "price": "77.62"
  },
  {
    "id": "249",
    "product_id": "200051",
    "sku": "6009195203320",
    "prod_name": "Salted Butter 500g",
    "price": "76.95"
  }

]

javascript arrays

Answer 1

Answer №1

In case you are searching by product_id, the solution provided will retrieve the data in Object form. If you prefer to receive the data in an Array format, you can utilize filter() instead of find().

var search = product_details.find(detail => {
    return detail.product_id === "199291";
});

The resulting output will be as follows:

{
     id: "220"
     price:"9.99"
     prod_name:"Medium Carrots 500g"
     product_id:"199291"
     sku:"20008307"
 }

Answer №2

To check for the presence of each product_id in product_details, you can achieve this by using a combination of two nested for loops.

For instance:

for(let x=0; x<product_id.length; x++){
    for(let y=0; y<product_details.length; y++){
      if(product_id[x].product_id === product_details[y].product_id){
        console.log(product_details[y]);
      }
    }
}

I believe this approach should work well for your scenario. Best of luck!

Answer №3

To streamline the process, you can link each product_id and retrieve the initial match in the product_details array

product_id.map(a=>({...a, ...product_details.find(b=>b.product_id == a.product_id)}))

If needed, you also have the option to eliminate those that don't align by adding .filter(a=>a.id)

var product_id = [{
    "order_id": "281774",
    "product_id": "203751",

  },
  {
    "order_id": "281774",
    "product_id": "198999",

  },
  {
    "order_id": "281774",
    "product_id": "199291",

  },

  {
    "order_id": "281774",
    "product_id": "256156",

  }
];

var product_details = [{
    "id": "219",
    "product_id": "198999",
    "sku": "20148089",
    "prod_name": "Chocolate Mousse 1L",

    "price": "39.99"
  },
  {
    "id": "220",
    "product_id": "199291",
    "sku": "20008307",
    "prod_name": "Medium Carrots 500g",

    "price": "9.99"
  },
  {
    "id": "221",
    "product_id": "204759",

Answer №4

I'm not entirely certain if this is the optimal method, but it's my go-to approach for searching for an element within an array.

function findItemInArray(itemsArray, itemId){
for(item of itemsArray){
    if(item.itemId === itemId){
        return item;
    }
}
}

I didn't quite catch your message. How about giving this a try?

product_id.forEach(prod => {
  if (prod) {
    product_details.forEach(detail => {
      if (detail && detail.product_id === prod.product_id) {
        console.log(detail)
      }
    })
  }
})
