Self is an object-oriented, dynamic programming language based on the Smalltalk programming language. It was developed at Xerox PARC in the 1980s.
Self was designed to be simple, efficient, and easy to learn. It is based on the principle of "object-oriented programming", which is a style of programming that focuses on objects and their interactions.
Self is dynamically typed, meaning that variables can hold values of any type. This makes it easy to write programs quickly, but can also lead to errors if the types of variables are not carefully checked.
Self has a small set of core features, which makes it easy to learn. However, its powerful object-oriented features give it the flexibility to be used for a wide range of programming tasks.
Self is an ideal language for prototyping and experimentation. It is also well suited for writing programs that are easy to understand and maintain.
