snippet for creating object from destructured array

Question

For example, I had an array with 3 numbers:

var arr = [124, -50, 24];

and I need to convert this array to the object:

{
   x: 124,
   y: -50,
   z: 24
}

I don`t want to use "old-style" syntax for this, for example:

{
  x: arr[0],
  y: arr[1],
  z: arr[2]
}

so for now, I`m using that syntax:

const [x, y, z] = [...arr];
const obj = {x, y, z};

But, is there is any way to do this with a straight dectructuring array to object without need of temporary variables?

Answer 1

As it was already mentioned in the comment you can use an Immediately Invoked Function Expression (IIFE) to create the object in a single step, but it's less readable then multiple steps.

const arr = [124, -50, 24];
const obj = (([x, y, z]) => ({ x, y, z }))(arr);

console.log(obj);
