Number one this week, Elsa is a new JavaScript runtime written in Go.
Whereas Node.js and Deno use the V8 JavaScript engine, it’s built on top of QuickJS a “small and embeddable” Javascript engine that supports the latest specification of the language (ES2020).
Source files are bundled with esbuild a JavaScript bundler also written in Go. According to the benchmarks, esbuild bundles files a lot faster than the most popular solutions: Webpack, Parcel, Rollup, and Fusebox.
Like Deno, Elsa supports natively TypeScript files and lets you import any file from simple URLs (similar to the good old <script> tag in the browser).
Be aware that the project is at a very experimental stage.
