Function isPlainObject

Checks if a given value is a plain object.

A plain object is an object created by the {} literal, new Object(), or Object.create(null).

This function also handles objects with custom Symbol.toStringTag properties.

Symbol.toStringTag is a built-in symbol that a constructor can use to customize the default string description of objects.
