Answer 1

Destructuring makes this easy:

const yourArray = ['Jimbo', '555-555-5555', '[email protected]'];

const [name, phone, email] = yourArray;
const yourObject = { name, phone, email };

console.log(yourObject);

The first statement pulls items out of the array and assigns them to variables. The second statement creates a new Object with properties matching those variable names + values.

If you wanted to convert an Array of Arrays, simply use the same technique with map:

const peopleArrays = [
  ['Jimbo', '555-555-5555', '[email protected]'],
  ['Lakshmi', '123-456-7890', '[email protected]']
];

const peopleObjects = peopleArrays
  .map(([name, phone, email]) => ({ name, phone, email }));

console.log(peopleObjects);

Answer 2

Another solution is to use Object.fromEntries - link

const keys = ['name', 'phone', 'email'];
const values = ['jonas','0302323','[email protected]'];

const result = Object.fromEntries(keys.map((key, index) => [key, values[index]]))
