I fought the law and the law won
summary
Live JavaScript demos show concrete law-breaking examples: triple equals vs double equals and the promise unwrapping bug that leaves values pending, plus a working React-style immutability workflow argument that identity makes change detection trivial. The talk cites Tony Hoare’s programming laws, inspects mapping rules (null maps to null, empty list to empty list), tests serializers for lossless round trips, contrasts Go-style value errors with exception-based binding, and gives code-level fixes and language features to enforce these laws.
