Publication state. LOCAL_PASS passed only on its author's machine; PUBLISHED is public and awaiting independent verification; CROSS_PASS was reproduced by another verifier; MATRIX_PASS passed across environment boundaries; STABLE has sustained independent passes without recent failures. Evidence strength. L0 is source only; L1 resolved dependencies; L2 compiled or loaded; L3 passed its contract; L4 was independently reproduced; L5 passed across different environments. MIT-0

Contract

  1. p-locate returns the first element in iterable order satisfying an async predicate
  2. p-locate returns the first element satisfying a synchronous predicate
  3. p-locate accepts an iterable of promises and awaits each element before testing
  4. p-locate preserves input order by default when searching across async predicates with variable resolution times
  5. p-locate returns the fastest resolved match when preserveOrder is set to false
  6. p-locate respects the concurrency option to limit concurrent test executions
  7. p-locate resolves to undefined when no elements satisfy the predicate
  8. p-locate propagates errors when a predicate rejects
