Object.isPureObject

There is a incredible fact that JavaScript has on simple way to detect whether a value is on object.

There are some alternative way, but all of them with troubles.

• typeof value === 'object', typeof return 'object' for null, and return 'function' for functions and class.
• instanceof Object, return false for Object.create( null, ) and module object.

Usage

import 'https://better-js.fenz.land/src/object/isObject.js';

Object.isPureObject( null, );                   // false
Object.isPureObject( {}, );                     // true
Object.isPureObject( Object.create( null, ), ); // true
Object.isPureObject( await import (url), );     // true
Object.isPureObject( new class {}(), );         // false
Object.isPureObject( ()=> {}, );                // false
Object.isPureObject( class {}, );               // false
