Yeah this is a great deeper dive. Do we surface this or something like it anywhere in the guides? I know there’s the section on “Autotracking In-Depth”. I’m never quite sure how deep to go. Too much information can be overwhelming but not enough can be confusing.
So I guess that begs the question do you @chriskrycho and @ijlee2 have a recommendation for what to use as the go-to “introductory” version of a tracked array? I took that version from the original tracked RFC and it’s slightly awkward as you mention but it also seems fairly clear just from the code what/why it’s necessary. TrackedArray is great but obviously that currently requires an addon and it’s a new class instead of a POJA which can be a turn-off to some. So for my own reference what would be your first recommendation if someone is learning and just wants to get a tracked array going and worry about the rest later?
