[RxJS] AuditTime & throttleTime

auditTime:

import { fromEvent } from 'rxjs';
import { auditTime, map } from 'rxjs/operators';

const click$ = fromEvent(document, 'click');

click$
  .pipe(
    /*
     * auditTime will begin window when the source emits. Then,
     * once the window passes, the last emitted value
     * from the source will be emitted. For instance, in this
     * example if you click a 4s timer will be started. 
     * At the end, the last click event during that window
     * will be emitted by auditTime. This is similar to the
     * behavior of throttleTime, if you were to pass in a config
     * to emit the value on the trailing edge.
     */
    auditTime(4000),
    /*
     * adding mapping to stackblitz example since logging
     * raw events is flaky
     */
    // @ts-ignore
    map(({clientX, clientY}) => ({clientX, clientY}))
  )
  .subscribe(console.log);

throttleTime: leading: false, tailing: true:

In face: auditTime is the same as throttleTime with trailing true:

throttleTime(500, asyncScheduler, {leading: false, trailing: true})

the same as 

auditTime(500)
