> I want to build web apps with low memory, cpu, and bandwidth profile. Give us a simpler language that doesn’t need crazy complicated hotspot profiling JITs. Just make the default, simple thing insanely fast. What makes you think it isn't? What if I told you that people were creating Electron-style apps over a decade before Electron ever existed? Go use Firefox 0.8 or Netscape 6. Pretty much every part of the UI on your screen that you'll interact with is backed by JavaScript. Keep in mind that this was 15–20 years ago, pre-Windows Vista, where main memory wasn't measured in gigabytes. And that was all pre-JIT! Here's a screenshot of the file listing for the version of AOL Instant Messenger that was built into Netscape Navigator: https://imgur.com/a/ztaMVon https://imgur.com/a/ztaMVon And a shaky cellphone video of someone using it over 10 years later, before AOL shut down the network: https://www.youtube.com/watch?v=apyR0bPnFAo https://www.youtube.com/watch?v=apyR0bPnFAo > Esbuild is like 20x faster than webpack. The problem is webpack and the development style favored by the NodeJS/NPM community. It's filled with bad practices, and they all do it because either no one knows better, or they don't care. JS is not inherently slow. It's exceptionally fast, even. Contrary to popular belief, though, how you write code still matters. The myth of the sufficiently smart compiler (including JITs) is that: a myth.
