In programming, what is a kitchen sink?

In programming, the term "kitchen sink" generally refers to a programming language feature or library that includes a large number of unrelated, often unnecessary, and sometimes even contradictory functions, options, or capabilities.

The term is used to describe something that is overly comprehensive, including everything and the kitchen sink. When a library or framework has too many features that aren't necessarily related or needed, it's often criticized as being a "kitchen sink" library.

Such a library may be seen as bloated and difficult to use, and may lead to decreased performance, increased complexity, and reduced maintainability. In general, it's often better to use libraries and frameworks that are specialized and focused, rather than ones that try to do everything at once.
