Buffer,  FlatMap,  GroupBy,  Map,  Scan, and  Window

Filtering Observables

Debounce,  Distinct,  ElementAt,  Filter,  First,  IgnoreElements,  Last,  Sample,  Skip,  SkipLast,  Take, and  TakeLast

Combining Observables

To

Connectable Observable Operators

Backpressure Operators

a variety of operators that enforce particular flow-control policies

These pages include information about some operators that are not part of the core of ReactiveX but are implemented in one or more of language-specific implementations and/or optional modules.
