What is is-plain-object?

The is-plain-object package is a simple utility that checks if an object is a plain object, that is, an object created by the Object constructor or one with a null prototype.

What are is-plain-object's main functionalities?

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 objects created by other constructors.

const isPlainObject = require('is-plain-object');

const obj = { x: 1, y: 2 };
console.log(isPlainObject(obj)); // true

const notPlain = Object.create(null);
console.log(isPlainObject(notPlain)); // true

function Test() { this.a = 1; }
console.log(isPlainObject(new Test())); // false

Other packages similar to is-plain-object

lodash.isplainobject

This package is a part of the Lodash library specifically for checking if a value is a plain object. It is similar to is-plain-object but comes from a well-known utility library, which might be preferable for projects already using Lodash.

isobject

Isobject checks if a value is an object and not null, but it does not check if the object is plain. It is less strict compared to is-plain-object, which specifically checks for plain objects.
