| # buffer | |
| Collects values from a source stream until a `trigger` stream fires and the | |
| collected values are emitted. | |
| # concat | |
| Appends the values of a stream after another stream finishes. | |
| # debounce, debounceBuffer | |
| Prevents a source stream from emitting too frequently by dropping or collecting | |
| values that occur within a given duration. | |
| # merge, mergeAll | |
| Interleaves events from multiple streams into a single stream. |
