How to convert array of arrays to array of objects where keys are taken from the first array?

Question

I have a variable that is returning an array of arrays, with each item in each array in double quotes.

var arrayOfArrays = [
  [ "Name", "Age", "Address" ],
  [ "A", "43", "CA" ],
  [ "B", "23", "VA" ],
  [ "C", "24", "NY" ]
]

I need to convert this to the following:

var arrayOfObjects = [
  {"Name":"A", "Age":"43", "Address":"CA"},
  {"Name":"B", "Age":"23", "Address":"VA"},
  {"Name":"C", "Age":"24", "Address":"NY"}
]

Update

Less verbose version using Array.prototype.reduce() with newer language constructs like destructuring and computed property names:

const arrays = [
  ["Name", "Age", "Address"],
  ["A", "43", "CA"],
  ["B", "23", "VA"],
  ["C", "24", "NY"]
];

const [keys, ...values] = arrays;
const objects = values.map(array => array.reduce((a, v, i) => ({...a, [keys[i]]: v}), {}));

console.log(JSON.stringify(objects));

Original answer

Using Array.prototype.slice(), Array.prototype.map() and Array.prototype.forEach():

const arrays = [
  ["Name", "Age", "Address"],
  ["A", "43", "CA"],
  ["B", "23", "VA"],
  ["C", "24", "NY"]
];

const keys = arrays[0];
const values = arrays.slice(1);
const objects = values.map(array => {
  const object = {};

  keys.forEach((key, i) => object[key] = array[i]);
  
  return object;
});

console.log(JSON.stringify(objects));
