How to rearrange array of objects to new array of Objects

I have an array of objects with the same keys, example:

const data = [{name: "firstName", value: "John"},
{name: "lastName", value: "Smith"},
{name: "Number", value: "421-8686"}
]

I however want the values to become the key and values. example:

const data = [{"firstName": "John"},
{"lastName": "Smith"},
{"Number": "421-8686"}]

I tried a few methods, but for some reason or another I fail. My latest attempt is:

   let newData = {}
    arrayData.forEach((item, index) => {
      let key = data.name
      let value = data.value
      newData[index] = { key: value} // this results in {"key": "John"} --> but i want {"firstName": "John"}

});

Solution

  • You can use Object.fromEntries.

    let data = [
  {name: "firstName", value: "John"},
  {name: "lastName", value: "Smith"},
  {name: "Number", value: "421-8686"}
]

data = data.map(info => Object.fromEntries([[info.name, info.value]]))

console.log(data)
