Factor is a modern concatenative language where all computation operates on a data stack and programs are built by composing named words. It features an image-based development environment, a JIT compiler, and a comprehensive standard library covering web, crypto, and parsing. Its quotation-based higher-order functions make functional patterns natural and concise.
