isEmpty

Problem

You need a single guard for all "has no content" states — empty string, empty array, empty object, empty Map, or empty Set.

Solution

Use isEmpty(value) to check whether a value has no meaningful content.

import { isEmpty } from '@vielzeug/arsenal';

isEmpty(''); // true
isEmpty([]); // true
isEmpty({}); // true
isEmpty(new Map()); // true
isEmpty(new Set()); // true

isEmpty('hello'); // false
isEmpty([1]); // false
isEmpty({ a: 1 }); // false
