JS needs a standard library that ships in all the browsers. "There, you're all using the same tools. They're not perfect for any of you but they're good enough for all of you."

I noticed recently that module support is now in chrome. When module support lands for all the browsers, it's going to be a huge step toward getting rid of a lot of build complexity.

I've been writing vanillajs toys the past month and wow have things improved greatly in the last four years.
