Check if a value is a plain object
An object is plain if it's created by either {}, new Object(), or Object.create(null).
npm install is-plain-objimport isPlainObject from 'is-plain-obj';
import {runInNewContext} from 'node:vm';
isPlainObject({foo: 'bar'});
//=> true
isPlainObject(new Object());
//=> true
isPlainObject(Object.create(null));
//=> true
// This works across realms
isPlainObject(runInNewContext('({})'));
//=> true
isPlainObject([1, 2, 3]);
//=> false
class Unicorn {}
isPlainObject(new Unicorn());
//=> false
isPlainObject(Math);
//=> false
