Dive into the world of Forth programming language in this comprehensive 44-minute tutorial for beginners. Explore the importance of Forth in understanding stack machines, WebAssembly, Bitcoin, blockchain, and smart contracts. Learn how this old programming language provides insights into fundamental computer science concepts and modern technologies. Start with installing gForth and get hands-on experience with stack operations, arithmetic using postfix notation, and creating functions (words). Compare Forth to Bitcoin Script, examining the source code of early Bitcoin releases to understand Satoshi Nakamoto's programming background. Investigate the relationship between Forth and assembly language by analyzing an old Forth interpreter's source code. Gain a solid foundation in stack-based programming and discover how Forth's principles apply to cutting-edge technologies in this informative tutorial led by Chris Hay.
