$.isPlainObject()

Tests a value to see if it is a plain object, that was defined with {} and has a prototype of Object.

Usage

$.isPlainObject(obj);

obj

The value to be tested.

Returns

A boolean indicating whether the input value is a plain object.

Differences to jQuery

None.

Examples

This will return true because the object was created using object literal notation:

const myObject = {};
console.log($.isPlainObject(myObject));
// Expected output: true

This will return false because an array’s prototype is Array, not Object:

const myArray = [];
console.log($.isPlainObject(myArray));
// Expected output: false

This will return false because a Date object’s prototype is Date:

const myDate = new Date();
console.log($.isPlainObject(myDate));
// Expected output: false
