API Reference

last()

last: emit the last value matching pred (or the last value) on the source's COMPLETE. completeWhenDepsComplete:false + terminalAsRealInput:true. EDGE (RxJS divergence, flagged): RxJS last() throws EmptyError when no value matched; we COMPLETE without a value (no throw) — the clean-slate substrate has no "complete-or-throw" terminal and SENTINEL forbids emitting a placeholder.
