The third age of JavaScript: Three years in
summary
Thesis: JavaScript enters a consolidation phase driven by ES Modules replacing CommonJS and the practical end of IE11 (June 15, 2022), which lets browsers and CDNs assume modern features. Tooling shifts under the hood to tooling written in Rust and Go while user-facing shells remain JS (swc, Rome, dprint replacing Babel/Prettier/ESLint). Adoption patterns: Next.js and Turborepo win attention; cloud IDEs like StackBlitz and Gitpod rise. Problems and opportunities: bundle sizes up from ~100KB (2011) to ~500KB (2022), WebAssembly emergence, and new work around teaching, self-provisioning runtimes, and edge rendering.
