Metaprogramming in JavaScript
summary
Shows concrete metaprogramming techniques in JavaScript: adding/extending properties, using proxies and forwarding versus delegation, and a small extend/rename library as proof of concept. Explains setPrototype, noSuchMethod, closures and partial evaluation, and demonstrates runtime-built artifacts (a dynamic balancer and a debounce) that operate on real objects using before/after/around interception to decorate methods.
