    Params: Name Type Attribute Description comparer Function optional Optional comparer function that it will use instead of its default to compare the value of two items. We subscribe to that same observable, and on success we calculate the new list of todos by adding the new todo to the current list. Example: Emit the number 7, then complete. Remember, Observables producing the values Asynchronously. Initially, the timer is disabled. The from operator iterates over each character of the string and then emits it. Params: Name Type Attribute Description addHandler function handler: Function : any A function that takes a handler function as argument and attaches it somehow to the actual source of events.

    In this observable example we are instead going to make the object and transform the item via a function.See: filter first findIndex take.

    For instance, you may have an observable of click events that you wish to transform into an observable of objects containing just the clientX and clientY.Use forkJoin with project function.

    This is what bridges an Observable with the iterable pattern, we have to convert our array of JSON objects from filmha2.online() to an Observable stream.If the Promise resolves with a value, the output Observable emits that resolved value as a nextand then completes.

    Any Iterable types like Generator functions can be converted into an observable using from the operator. 1. 2. 3. 4. 5. 6. 7.Also, if you use publish or publishReplay with a ConnectableObservables refCount operator, you can simply use share and shareReplay respectively, which chain these two.

    Converts an Observable of Notification objects into the emissions that they represent. var timer2 = filmha2.onlineal().take(6); var timer3.Thus, as usual, each subscription to this stream triggers subscription to the source Observable.

    The toPromise function lives on the prototype of Observable and is a util method that is used to convert an Observable into a Promise.If the Promise is rejected, then the output Observable emits the corresponding Error.

    Don't pipe. It's on the Observable object by default. filmha2.online('foo').toPromise(); // this. rxjs5 import 'rxjs/add/operator/toPromise';.Returns an Observable that skips all items emitted by the source Observable as long as a specified condition holds true, but emits all further source items as soon as the condition becomes false.

    With the introduction of async/await syntax, Promise is getting so popular. But if you work with Angular, you'll probably need an Observable.Note that you do not get any access to errors emitted by the Observables.

    We could go even further, for instance the loading property could be its own observable, how far and how deep to go is up to you.

    In both cases function or method will be called when subscription to Observable is being cancelled and should be used to clean up all resources.

    If the source Observable terminates with an error, count will pass this error notification along without emitting a value first.

    The reason for the term Switch Let's now learn why the term switch is used to name the switchMap operator, by breaking down this output step-by-step: just like in the case of the HTTP example, nothing will happen until the result observable is subscribed to the source observable will then emit the first value FB-1 0 the source value will be mapped into an inner observable, which is the output of the mapping function passed to switchMap that inner observable will be subscribed to the result observable will emit the values also emitted by the inner observable we can see that the inner observable is emitting the values 0, 1, 2 that are the output of newly created interval Why the term Switch?

    If called with no arguments, first emits the first value of the source Observable, then completes.
