이 네트워크가 제공하는 것은 하나입니다. 빌드되는 샘플. 샌드박스에서 돌리고 서명된 영수증을 보관합니다. 등급을 매기지 않고 무엇도 보증하지 않습니다 — 같은 코드가 당신 환경에서 빌드되는지는 측정한 적이 없습니다. 통과한 계약 영수증을 낸 서로 다른 서명 키의 수입니다. 하나면 작성자 혼자이고, 둘 이상이면 다른 사람도 빌드했다는 뜻입니다. 키는 스스로 만드는 것이고 뒤에 등록된 신원이 없으므로, 세는 것은 사람이 아니라 키입니다. MIT-0

컨트랙트

  1. assert setting NaN on an atom holding NaN is a no-op under Object.is and triggers zero notifications, whereas strict inequality (!==) in earlier versions triggered notifications
  2. assert setting -0 on an atom holding 0 notifies listeners because Object.is(0, -0) is false, whereas strict equality (===) treated them as identical
  3. assert overriding $atom.eq allows custom equality functions to suppress listener notifications and keep previous object references when values are semantically identical
  4. assert map.eqKey compares existing and incoming field values with Object.is(prev, next, key), skipping object cloning and listener notification when values match
  5. assert an uncaught error thrown inside one listener during notify does not abort the notification loop: all subsequent listeners in the queue still execute before the error is rethrown
  6. assert effect runs immediately upon registration with unpacked positional arguments, mounts all passed stores by incrementing their listener counts, and executes cleanup functions before re-runs and on disposal
  7. assert onSet interceptors execute in reverse registration order (reduceRight) and pass a mutable shared context across interceptors
  8. assert calling abort() inside an onSet interceptor halts the mutation before store value update and notifies zero listeners
  9. assert onNotify interceptors can abort listener notifications while keeping the store value update intact
  10. assert onStart fires synchronously upon first subscription, onStop fires synchronously upon the last unbind, whereas onMount unmount cleanup is deferred by STORE_UNMOUNT_DELAY (1000ms)
  11. assert batched defers recomputations across rapid dependency updates via timer debouncing while computed recalculates synchronously on every change, and reading batched with .get() synchronously flushes the calculation
  12. assert subscribeKeys immediately primes the listener with current store value whereas listenKeys only fires on subsequent mutations, and listenKeys matches nested prefix keys upon dotted path updates
  13. assert mapCreator returns cached singleton stores by id while active and automatically evicts cached instances once unmounted after STORE_UNMOUNT_DELAY
  14. assert setPath and setByKey are immutable data transformation utilities that return cloned objects without mutating the original source, while getKey safely traverses nested paths from store state
  15. assert cleanStores resets store state in development mode and unmounts active stores synchronously
