How can i convert a javascript dynamic array to an array of multiple objects with custom key names

I have two fields in my table (name, role). I created a form where i can add and remove input fields dynamically using add and remove buttons using jquery. so the array i am creating is not a fixed width array. I am using map method to extract values of input items, but it is returning output as an array. Below is js function and output.

$('#save').on('click',function () {
const inputs = document.getElementsByClassName('form-control');

const newInputs = [...inputs]

// const extractedValues = newInputs.map((item) => {

const extractedValues = newInputs.map((item) => {

    return item.value;

});

console.log(extractedValues)

["John", "Manager", "bob", "Clerk", "Mike", "President"]

whereas i want to extract data as bulk objects as i want to submit this data to and api spring boot api endpoint. API is working fine as i am able to insert multiple objects through postman.

How can i convert this data to an object (using item.name(key) and item.value(value)

[
{
"name": "John",
"role": "Manager"
},
{
"name": "John",
"role": "Manager"
},

JS File

$(document).ready(function () {
    
    
var html = '<tr class="newEntry"> <td> <input class="form-control" type="text" name="name[]" required=""> </td> <td> <input class="form-control" type="text" name="role[]" required=""> </td> <td> <input type="button" class="btn btn-danger" name="remove" id="remove" value="Remove"> </td> </tr>';

var x=1;

$('#add').click(function () {
    $("#table_field").append(html);
});

$('#table_field').on('click','#remove',function () {
    $(this).closest('tr').remove();
});



$('#save').on('click',function () {
const inputs = document.getElementsByClassName('form-control');

const newInputs = [...inputs]

// const extractedValues = newInputs.map((item) => {

const extractedValues = newInputs.map((item) => {

    return item.value;

});

console.log(extractedValues)

})

})

You can use reduce with four parameters to construct the [{ name: 'John', role: 'Manager' },{ name: 'bob', role: 'Clerk' }, { name: 'Mike', role: 'President' } ] objects array from the original ["John", "Manager", "bob", "Clerk", "Mike", "President"] array like below:

const extractedValues = ["John", "Manager", "bob", "Clerk", "Mike", "President"];
const result = extractedValues.reduce(function(acc, curr, index, array) {
    if (index % 2 === 0) {
       acc.push({name : array[index], role: array[index + 1]})
    }
    return acc;
}, []);
console.log(result);
