Prepack is a tool that optimizes JavaScript source code: Computations that can be done at compile-time instead of run-time get eliminated. Prepack replaces the global code of a JavaScript bundle with equivalent code that is a simple sequence of assignments. This gets rid of most intermediate computations and object allocations.
Thinking about going with PreactJs for dev.to
The dev.to web application has been built on "vanilla" JavaScript for performance purposes specific...
The many, many, many JavaScript runtimes of the last decade
This last decade has seen an inundation of new JavaScript runtimes (and engines in equal measure), enabling us to run JavaScript in all manner of contexts...
Emscripten: an LLVM-to-JavaScript compiler
Although the performance of today's JavaScript engines is sufficient for most web applications, faster and more predictable runtimes could be desired for performance-critical web code. Therefore, we present Speedy.js, a cross-compiler that translates ...

Speeding up the JavaScript ecosystem - eslint
Linting is the act of finding patterns in code that could lead to mistakes or ensure a consistent reading experience. It's a core piece of many JavaScript/TypeScript projects. We found lots of potential for time savings in their selector engine and AST conversion process and a perfect linter written in JS would be able to hit sub-second run times.
