import { of } from 'light-observable/observable'
import { skipLast } from 'light-observable/operators'

const stream = of(1, 2, 3, 4, 5).pipe(
  skipLast(2)
)

stream.subscribe(console.log)
/*
 -> 1
 -> 2
 -> 3
*/

Also available as an Observable creator:

import { skipLast, of } from 'light-observable/observable'

const stream = skipLast(2, of(1, 2, 3, 4, 5))

stream.subscribe(console.log)
/*
 -> 1
 -> 2
