Reactivity: an early draft of *everything* we've learned since Octane

[NullVoxPopuli]

wip, no looking, shhh

Rendered

What finally motivated me to get this going:

• https://twitter.com/sveltejs/status/1704496039468605842
  • Svelte announcing Runes, a runtime reactivity system that wraps Signals (allegedly)
• https://twitter.com/Rich_Harris/status/1704545067640177000
  • Svelte folks confused by the lack of magic, but explained well in brief, eliminating the confusion

TODO:

• propose primitives

  • [ ] reactive values with cleanup (aka resources)
  • [ ] tracked promises
  • [ ] localCopy
  • [ ] tracked object / array / map / set
  • [ ] deep
  • the libraries to merge (as separate imports as to not force the need for tree-shaking)

      • ${}/async
    • https://github.com/NullVoxPopuli/ember-resources/
      • ${}/resource

• propose flexibility

  • [ ] value-based equality checking (as opt-in, can can cost performance (but this is for situations where reference based invalidation is less performant))
