how to remove key values in array of objects-CodePudding

I am having a array of objects which looks like this

var data = [
    {
        "id": "K014-s1",
        "status": true,
        "amount": 992,
        "check": true,
      
    },
    {
        "id": "K014-s2",
        "status": false,
        "amount": 10992,
        "check": true,
       
    }
]

I want only certain key values from the object in the array

Required Output:

 var data = [
        {
            "id": "K014-s1",
            "amount": 992,
        },
        {
            "id": "K014-s2",
            "amount": 10992,
        }
    ]

Code I tried:

     var filteredData = []
        var result = data.map((obj) => {
        filteredData.push(obj.id)
        })

console.log(filteredData)

I tried. But don't Know how to make it. Please Help me with some solutions

CodePudding user response：

instead of pushing object to another array,you can simply map your data like this

    var result = data.map((obj) => {
        return {
                id:obj.id,
                amount:obj.amount
               }
    })

CodePudding user response：

Array.prototype.map already creates a new array, so result will already be the new value you are looking for.

The map() method creates a new array populated with the results of calling a provided function on every element in the calling array.

var filteredResult = data.map((obj) => {
   //additional logic, if needed here.
   return {
      id: obj.id,
      amount: ob.amount,
   }        
})

Alternatively you can of course use a for loop or array.prototype.forEach to achieve the same:

var filteredData = []
data.forEach((obj) => {
  filteredData.push({
    id: obj.id,
    amount: ob.amount,
  })
})
