The JavaScript ecosystem is delightfully weird
Coffeescript was well before "tree shaking" (the JS ecosystem's way of spelling "dead code removal") and code splitting, both being relatively new things in the bundler world ("tree shaking" being introduced with rollup if memory serves). Then came Acorn, which gave way to a whole slew of JS transformation bits.It also didn't help that Node was fixed at 0.12 for years and years, and we had the IO.js fork until Node was released by Joyent for OSS community members to take over. That caused more issues to boot.Also the whole bundling fiasco started with Babel, which wasn't a bundler at all and instead started as a means to provide polyfills for supporting "old browsers" (really, IE). From that whole thing came the concept of "evergreen browsers" which is a term that has largely fallen out of the common vocabulary with the rise of Edge.Now we have "anything is a valid feature request" TC-39, and "it's really just Google at this point" browsers dictating how the web works.It's a nightmare. As a maintainer of several large JS packages, and being so dreadfully burnt out on JS, there are other words I'd use to describe the whole thing than "delightful".
