JS UX: Writing Code for Humans
summary
Watch if wanting concrete API rules plus working demos: claims like documentation is the last resort, concrete fixes (sensible defaults, accept multiple input types, avoid boolean traps, order params by importance), examples from native APIs (URL, SVG DOM, compareDocumentPosition), small tools and polyfills shown (chainvas, a multi-range polyfill, Prism, fetch usage, MutationObserver for responsive layout), evidence from dozens of open source projects with thousands of merged pull requests, and actual replacements that remove error cases. Ignore if only looking for high‑level UX theory.
