Introduction to Roc Programming Language by Richard Feldman

Richard Feldman introduces the Roc programming language as a fast, friendly, and functional language in active development, featuring a small ecosystem. He covers Roc's syntax, emphasizing assignments, list.map, and lambdas, while highlighting its purely functional nature. Roc's error handling and type inference capabilities are discussed, showcasing how the compiler infers types and prevents errors from spreading. Roc supports different workflows, accommodating both low ceremony and robust error handling approaches. The platform design allows for standalone executable builds with secure IO primitives, enabling safe execution of scripts downloaded from the internet. Despite being a work in progress with occasional compiler crashes, Roc has inspired Richard, particularly for projects beyond front-end web development.
