How do you return new Observable(function(observer) { ... with RxJS v5?
<p>I am trying to replace all the promises that my functions return with Observables. From this post, I learned that I should no longer use "new Observable" <a href="https://stackoverflow.com/questions/35676451/observable-forkjoin-and-array-argument">Observable.forkJoin and array argument</a></p>

<p>What is the RxJS v5 syntax to achieve this as such to achieve asynchronous waiting?</p>

<pre><code>thirdFunction() {

    let _self = this;

    return new Observable(function(observer) {

        ...

        observer.next( responseargs );
        observer.complete();
    });
}
</code></pre>

<p>Thank you greatly for help you can offer.</p>
