What is the best way to assign multiple values to certain elements within an array?

Question

What is the best way to assign multiple values to certain elements within an array?

I have an array that looks like this:

   items = {
      item1: 10,
      item2: 5,
      item3: 7,
      item4: 3,
   };

I am looking to include additional details in this array, for example:

       items = {
          item1: 10 {available: true},
          item2: 5 {available: false},
          item3: 7 {available: true},
          item4: 3 {available: true},
       };

I've attempted various methods such as:

items.item2.available = true;

However, I did not see any changes in the array.

Is there a proper way to achieve this? Or is there a more effective approach to solving this problem?

It seems like there may be some confusion in your question as you mentioned wanting an array ([]) but shared code for an object ({}). However, if I understand correctly, you can achieve the desired result by using an object where each key contains an array of values. Here is an example:

const obj = {
  name: [1],
  address: [1],
  phone: [2],
  email: [5],
};

obj.email.push(true);
obj.email.push("whatever");

console.log(obj)
console.log(obj.email[1])
console.log(obj.email[2])

Therefore, while obj itself is an object, name, address, phone, and email are arrays that can be extended using array methods.

In the initial data structure, adding data in a specific way is not possible. Therefore, one must create an object with the required data structure first. Subsequently, the original data needs to be transferred to the new object before new data can be added.

     newObj.name.push(origObj.name,true,"something1","something2");
     newObj.address.push(origObj.address,false);
     newObj.phone.push(origObj.phone,true);
     newObj.email.push(origObj.email,true);

Output:

{
"name":[1,true,"something1","something2"],
"address":[1,false],
"phone":[2,true],
"email":[5,true]
}

Original Object:

    var origObj = {
        name: 1,
        address: 1,
        phone: 2,
        email: 5
    };

New Object:

    var newObj = {
        name: [],
        address: [],
        phone:[],
        email: []
    };

        address: [],
        phone:[],
        email: []
    };

To properly categorize each element in an array, you should assign a variable and use a function for classification. For instance,

const groceries = ['milk', 'eggs', 'bread'];
console.log(groceries);
