I am using Haxe, which is a complete different ecosystem, which compiles to JS. It has a fast optimizing compiler, a strict-typed language. Has features like meta programming /syntax-transformation (macros), conditional compilation, inlined calls etc. These are great tools to create high performance apps. You can find all the features on its website. It has a formatting tools and a linter, but has build-in deadcode elemination and a static analyzer so it only includes everything you use (so no need to strip it off afterwards as seen in some JS tools). Also could be a good candidate for WASM, since it compiles to C++. One thing that is great about Haxe is that is also compiles to other languages; you can reuse same code for different compiler targets. I mean, why does Rome only target JavaScript? For Haxe that's just one option. [disclaimer, I am a big Haxe fanboy]
