How to convert value into key & another key into value in JavaScript [duplicate]

Question

This is my array of Object. I want to convert my first value into key & Second value into value only. Please go through question and i have also attached my desired output.

 [
  {
    "name": "Unknown",
    "value": "RAHUL"
  },
  {
    "name": "FirstName",
    "value": "WILLEKE LISELOTTE"
  },
  {
    "name": "LastName",
    "value": "DE BRUIJN"
  }
]

I want my Object as

{
"Unknown": "RAHUL"

},
{
"FirstName": "WILLEKE LISELOTTE"
},
{
"LastName": "DE BRUIJN"
}

I want my Object as that's not an object, it's several objects separated by commas — StudioTime

IF you mean to create a new array, then simply map the original array. You don't need to create a new array and push into it, that's just redundant code:

const testData = [{
    "name": "Unknown",
    "value": "RAHUL"
  },
  {
    "name": "FirstName",
    "value": "WILLEKE LISELOTTE"
  },
  {
    "name": "LastName",
    "value": "DE BRUIJN"
  }
];

const newData = testData.map(nameObject => {
  return {
    [nameObject.name]: nameObject.value
  }
});
console.log(newData);

You just have to use brackets for [value.name] to perform achieve this.

var arr = []

testdata.map((value) => {
    arr.push({ [value.name]: value.value })
})

You asked a question then you answered it yourself? why asking if you already have the answer?

Andreas Over a year ago

@AdilBimzagh That's totally valid. Although in this case there are definitely already multiple other questions with the exact same problem.

This results in an array. OP said he wants an object.

Andreas Over a year ago

@James This is the OP o.O

@Andreas understood. Point still stands.
