Check if an object is a plain object

This feature allows you to verify if a given object is a plain object. It returns true for objects created by the Object constructor or with a null prototype and false for all other types of objects, such as instances of custom classes or built-in JavaScript objects like Map.

const isPlainObj = require('is-plain-obj');

console.log(isPlainObj({foo: 'bar'})); // true
console.log(isPlainObj(new Map())); // false
