Answer 1

You can use Array.from with a mapping function to convert each value inside your set into an object and then use Object.assign() with the spread syntax to merge the array of objects into a single resulting object like so:

const uom = new Set(['inches', 'centimeters', 'yards', 'meters']);
const res = Object.assign(...Array.from(uom, v => ({[v]:''})));
console.log(res);
