Is skipWhile working correctly?

Hi there!

I am probably misunderstanding how skipWhile works, but I am hoping you can help me understand.

Here's some code that illustrates my question:

const obs = Rx.Observable.of(1, 2, 3, 4)

obs
  .skipWhile((x) => x < 3)
  .subscribe((x) => console.log(x))

// Console logs: 3 4

console.log("----")

obs
  .skipWhile((x) => (x % 2) === 0)
  .subscribe((x) => console.log(x))

// Console logs: 1 2 3 4
// Expected: 2 4

JSBin here: http://jsbin.com/jefurosuwo/4/edit?js,console Using rxjs 5.4.2.

Thanks! <3

RxJS 5 is maintained at https://github.com/ReactiveX/rxjs/

But yes that appears to be correct behavior. skipWhile should skip events until the predicate evaluates to false and then it should emit the value that triggered the switch as well as all subsequent events.

Thanks @paulpdaniels. Closing this.
