Utilize JavaScript to transform an array into an object using destructuring

Is there a more efficient method to convert a deconstructed array into an object in JavaScript?

My current approach involves using the axios API library, and when I make multiple queries simultaneously, I receive an array with 4-5 API responses. I then need to transform these responses into an object and pass them to another function. Is there a shorter way to accomplish this task? It's not a major issue, but I have numerous instances of this in my application.

const [foo, bar, baz] = [1, 2, 3]
const obj = { foo, bar, baz }
console.log(obj)
=> {foo: 1, bar: 2, baz: 3}

A handy method called toObj makes use of Object.assign along with map

const toObj = (arr, keys) =>
  Object.assign({}, ...keys.map((key, i) => ({ [key]: arr[i] })));  
  
const arr = [4, 5, 6]
const keys = ['alpha', 'beta', 'gamma'];

console.log(toObj(arr, keys));

Manually declaring the object and props is often the most concise vanilla JavaScript approach. However, if you prefer using libraries, Lodash offers a zipObject method that can achieve the same result in a more streamlined manner, such as:

_.zipObject(['apple', 'banana', 'orange'], [5, 10, 15])

If you're looking for a solution in JavaScript, there isn't a built-in method that fits your exact needs. However, creating a custom function to achieve this is quite simple. Here's an example inspired by _.zipObject from the Lodash library:

function createObject(keys, values) {
  return keys.reduce((object, key, index) => {
    object[key] = values[index];
    return object;
  }, {});
}

console.log(createObject(['one', 'two', 'three'], [1, 2, 3]));

Here's a more concise version as a one-liner:

const createObject = (k, v) => k.reduce((o, c, i)=>(o[c]=v[i],o),{});
