skip：跳过前几个数据流

import { range } from "rxjs"
import { skip } from "rxjs/operators"
range(1, 10).pipe(skip(5)).subscribe(console.log)

skipWhile：根据条件进行数据流的跳过

import { range } from "rxjs"
import { skipWhile } from "rxjs/operators"
range(1, 10)
  .pipe(skipWhile(n => n < 5))
  .subscribe(console.log)

skipUntil：跳过数据源中前多少时间发出的数据流，发送从这个时间以后数据源中发送的数据流

import { timer, interval } from "rxjs"
import { skipUntil } from "rxjs/operators"
interval(100)
  .pipe(skipUntil(timer(2000)))
  .subscribe(console.log)
