Wiki Search Example will not cancel

[deanrad]

Hi - I'm very curious in using this project. But this looks like a bug:

Given: Most searches should be canceled when a new search term is done, and that's what I take is the intention of using switchMap.
When: A search is performed
Expected: The old search is canceled.
Actual: Because of the use of jQuery and Promises, the Observable returned from fetchTerm will not be canceled when the search term changes.

I don't have screen shots yet, but based on the code, that's what I believe the behavior will be.

If the rxjs ajax operators were used, cancelability would be built in. And it's not a good example to use jQuery just for something that rxjs already has.

I'm guessing JQuery/JSONP was used because of Wikipedia CORS. The following is relevant to doing that with RxJS: ReactiveX/rxjs#2095

And I just realized that JSONP will not cancel anyway, ha!

I slightly changed the example in #102
Should cancel search now 😅

Wow @NataliaTepluhina - that covers everything - thanks for jumping on that!
