However, it is frequently misunderstood as a technical tool for making cold hard guarantees about code, rather than as a human tool for signalling intent and setting expectations. Never is this more apparent than when we consider what a "breaking change" means. It's highly contextual: it depends on which language you're using, what your public interface is, what guarantees you've explicitly or implicitly made to users, how much software sits downstream of you, and so on. In this talk James will explore several ways you can accidentally break other people's JavaScript apps, how to avoid them, and what to do when you can't.

He created the open-source web messaging system Faye, whose internals now form the basis of much WebSocket tooling in the Ruby and JavaScript ecosystems. James also enjoys hacking on language tools, creating the cross-language parser generator Canopy, and a toy logic programming language called Infer. James is the author of the book JavaScript Testing Recipes, and am working on a second called Building Git, available in 2019.
