Turn array with two elements into JS object with one k/v-pair

Question

I have this array: ["description", "asc"]

and want to turn it into this object:

{ "description": "asc" }

What's the fastest way to achieve this?

I tried

const obj =  { array[0] : array[1] }

But it doesn't work because I can't seem to set the key of the object dynamically?

you can try this

const array = new Map([
  ["description", "asc"]
]);

const convobj = Object.fromEntries(array);

console.log(convobj)

You can do this:

let array = ["description", "asc"];
const obj = { [array[0]]: array[1] };
console.log(obj);
