# Time based operators comparison

RxJS offers a rich selection of time based operators but this diversity can come at cost when choosing the right operator for a task at hand. Below is a visual comparison of popular time based operators.

Compared operators:

* [auditTime](/learn-rxjs/operators/filtering/audittime.md)
* [bufferTime](/learn-rxjs/operators/transformation/buffertime.md)
* [debounceTime](/learn-rxjs/operators/filtering/debouncetime.md)
* sampleTime
* [throttleTime](/learn-rxjs/operators/filtering/throttletime.md)

```js
/*
interval      ^0-------1-------2-------3-------4-------5-------6-------7-------8-------9------|
auditTime     ^------------------------3-------------------------------7----------------------|
bufferTime    ^----------------[0,1]-------------------[2,3,4]-----------------[5,6,7]-[8,9]--|
debounceTime  ^------------------------------------------------------------------------9------|
sampleTime    ^----------------1-----------------------4-----------------------7--------------|
throttleTime  ^0-------------------------------4-------------------------------8--------------|
*/

// RxJS v6+
import { interval, merge } from 'rxjs';
import { auditTime, bufferTime, debounceTime, sampleTime, throttleTime, tap, take } from 'rxjs/operators';

const takeValue = 10;
const intrvl = 1000;
const time = 3000;

const intervaled = (operator, operatorName) =>
  interval(intrvl)
    .pipe(
      take(takeValue),
      operator,
      tap(x => console.log(`${operatorName}:${x}`))
    );

merge(
  interval(intrvl).pipe(take(takeValue), tap(v => console.log(`i: ${v}`))),
  intervaled(auditTime(time), "auditTime"),
  intervaled(bufferTime(time), "bufferTime"),
  intervaled(debounceTime(time), "debounceTime"),
  intervaled(sampleTime(time), "sampleTime"),
  intervaled(throttleTime(time), "throttleTime")
).subscribe();

// output
