An object-oriented operating system [1] is an operating system that is designed, structured, and operated using object-oriented programming principles. An object-oriented operating system is in contrast to an object-oriented user interface or programming framework, which can be run on a non-object-oriented operating system like DOS or Unix .
Objects are instances of a class. Object-oriented programming ( OOP) is a programming paradigm based on the concept of objects, [ 1] which can contain data and code: data in the form of fields (often known as attributes or properties ), and code in the form of procedures (often known as methods ).
This is misleading: the {} is interpreted as an empty code block instead of an empty object, and the empty array is cast to a number by the remaining unary + operator. If the expression is wrapped in parentheses - ({} + []) - the curly brackets are interpreted as an empty object and the result of the expression is "[object Object]" as expected ...

A Linux-based system is a modular Unix-like operating system, deriving much of its basic design from principles established in Unix during the 1970s and 1980s. Such a system uses a monolithic kernel, the Linux kernel, which handles process control, networking, access to the peripherals, and file systems.
An operating system ( OS) is system software that manages computer hardware and software resources, and provides common services for computer programs . Time-sharing operating systems schedule tasks for efficient use of the system and may also include accounting software for cost allocation of processor time, mass storage, peripherals, and ...
In computer science, an object is a programming element that has state, has associated operations and is accessed via an identifier . Object is a categorization into which many programming concepts fall. For example, an object can be a programming language variable, data structure, function, or method. In object-oriented programming (OOP), an ...
In object-oriented programming, inheritance is the mechanism of basing an object or class upon another object ( prototype-based inheritance) or class ( class-based inheritance ), retaining similar implementation. Also defined as deriving new classes ( sub classes) from existing ones such as super class or base class and then forming them into a ...
