jQuery isEmptyObject() method

The isEmptyObject() method is used to determine whether the passed argument is an empty object or not. It returns a Boolean value.

If it finds the passed value is an empty object, it returns true. Otherwise, it returns false. A plain object is created using the "{}" or by using "new Object". So, the isEmptyObject() method returns true if the objects are empty and are created using the "{}" or by using the "new Object()".
