Question

React

Is it possible in react-final-form-arrays to output data to an array and not an object?
By default it looks like this

{
  "customers": [
    {
      "firstName": "a"
    },
    {
      "firstName": "a"
    },
    {
      "firstName": "a"
    }
  ]
}

but I would like to

{
  "customers": [
    "a", "a", "a"
  ]
}
