nock

Nock is a minimalist programming language designed by John Carmack, known for his work on the video game Doom. It is notable for its simplicity and efficiency, using a minimal set of instructions to perform complex operations. Nock is stack-based, meaning it uses a stack to store data and manipulate it through a series of operations. The language consists of only three core instructions: "0", "1", and "2", which are used to manipulate the stack and perform computations. Nock is used primarily for its ability to represent and manipulate data structures, making it a powerful tool for certain types of computational tasks. Despite its simplicity, Nock has been used in various applications, including game development and cryptographic protocols. Its minimalist design allows for high performance and efficiency, making it an attractive choice for developers seeking a low-level programming language.
