Closure Compiler is the gold standard of optimizing JS compilers, but when I took a look in May 2019 there were a few issues.

  • Some type inferences aren't working quite well
  • GCC includes $jscomp polyfills for modern JS features like Maps/Sets and WeakMaps which Torus uses extensively, and especially when Torus targets modern browsers this tends to bloat the bundle size quite a bit (frequently over 2x)

I've @suppress'd my way through (1) but (2) seemed like a deal breaker and I couldn't figure out how to remove those polyfills given my limited time with it. May come back to it down the line as I play with Closure Compiler more.
