Summary
This one enforces modern JavaScript standards across ES2023+ projects, with a strong stance on async/await over callbacks and ESM over mixed module systems. It's built for vanilla JS work, Node.js backends, and browser APIs, with a five-step workflow that won't let you proceed past linting or coverage failures until you fix them. The constraint list is opinionated in a good way: no var, no synchronous I/O, no parameter mutation. Includes reference docs for async patterns, modules, and browser APIs. If you're tired of codebases that mix require() with import or skip error handling in async functions, this codifies the discipline to prevent that drift.
