      Ooo there's so many good ones for build speed not listed! 🔥📦🕸️ Limit usage of resolver capabilities (alias, modules, extensions) 🔥📦🕸️ Use /* webpackMode: "lazy-once" */ for import(`./some/${expr}`) in dev mode. 🔥📦🕸️ Use stats: errors-only if you don't need console feedbackhttps://twitter.com/addyosmani/status/1148479395692048384 …

      For errors-only, I just found this researching a tool called flamebearer. See how when stats are printed to console in their string form, it takes 24% of the build time. Trade-off: feedback is useful for diagnostic modes like debugging bundle size etc.pic.twitter.com/u4Jbrf4lnQ

      intl.js, not impl.js - I’m guessing this is ICU?

      It’s not quite ICU, it’s the old self-hosted implementation of the Intl.* APIs. We got rid of it in modern versions of @v8js: https://v8.dev/blog/intl#moving-away-from-self-hosted-js … cc @_gsathya
