We built Joist, an ActiveRecord-style ORM in TypeScript, on top of Facebook's dataloader library, and haven't had a single N+1 in ~4 years:

https://joist-orm.io/docs/goals/avoiding-n-plus-1s

Any "query in a loop", whether a manually-written `for` loop, or an "emergent for loop" from 100 `after_update` lifecycle hooks firing at once, are always auto-batched, every time.

Joist is also likely why we actually like GraphQL, vs. it generally having a reputation for being a pita to implement (N+1s everywhere w/o tedious, manual batching).
