/**
* Invokes an execution of an Observable and registers Observer handlers for notifications it will emit.
*
* <span class="informal">Use it when you have all these Observables, but still nothing is happening.</span>
*
* `subscribe` is not a regular operator, but a method that calls Observable's internal `subscribe` function. It
* might be for example a function that you passed to a {@link create} static factory, but most of the time it is
* a library implementation, which defines what and when will be emitted by an Observable. This means that calling
* `subscribe` is actually the moment when Observable starts its work, not when it is created, as it is often
* thought.
*
* Apart from starting the execution of an Observable, this method allows you to listen for values
* that an Observable emits, as well as for when it completes or errors. You can achieve this in two
* following ways.
*
* The first way is creating an object that implements {@link Observer} interface. It should have methods
* defined by that interface, but note that it should be just a regular JavaScript object, which you can create
* yourself in any way you want (ES6 class, classic function constructor, object literal etc.). In particular do
* not attempt to use any RxJS implementation details to create Observers - you don't need them. Remember also
* that your object does not have to implement all methods. If you find yourself creating a method that doesn't
* do anything, you can simply omit it. Note however, that if `error` method is not provided, all errors will
* be left uncaught.
*
* The second way is to give up on Observer object altogether and simply provide callback functions in place of its methods.
* This means you can provide three functions as arguments to `subscribe`, where first function is equivalent
* of a `next` method, second of an `error` method and third of a `complete` method. Just as in case of Observer,
* if you do not need to listen for something, you can omit a function, preferably by passing `undefined` or `null`,
* since `subscribe` recognizes these functions by where they were placed in function call. When it comes
* to `error` function, just as before, if not provided, errors emitted by an Observable will be thrown.
*
* Whatever style of calling `subscribe` you use, in both cases it returns a Subscription object.
* This object allows you to call `unsubscribe` on it, which in turn will stop work that an Observable does and will clean
* up all resources that an Observable used. Note that cancelling a subscription will not call `complete` callback
* provided to `subscribe` function, which is reserved for a regular completion signal that comes from an Observable.
*
* Remember that callbacks provided to `subscribe` are not guaranteed to be called asynchronously.
* It is an Observable itself that decides when these functions will be called. For example {@link of}
* by default emits all its values synchronously. Always check documentation for how given Observable
* will behave when subscribed and if its default behavior can be modified with a {@link Scheduler}.
*
* @example <caption>Subscribe with an Observer</caption>
* const sumObserver = {
* sum: 0,
* next(value) {
* console.log('Adding: ' + value);
* this.sum = this.sum + value;
* },
* error() { // We actually could just remove this method,
* }, // since we do not really care about errors right now.
* complete() {
* console.log('Sum equals: ' + this.sum);
* }
* };
*
* Rx.Observable.of(1, 2, 3) // Synchronously emits 1, 2, 3 and then completes.
* .subscribe(sumObserver);
*
* // Logs:
* // "Adding: 1"
* // "Adding: 2"
* // "Adding: 3"
* // "Sum equals: 6"
*
*
* @example <caption>Subscribe with functions</caption>
* let sum = 0;
*
* Rx.Observable.of(1, 2, 3)
* .subscribe(
* function(value) {
* console.log('Adding: ' + value);
* sum = sum + value;
* },
* undefined,
* function() {
* console.log('Sum equals: ' + sum);
* }
* );
*
* // Logs:
* // "Adding: 1"
* // "Adding: 2"
* // "Adding: 3"
* // "Sum equals: 6"
*
*
* @example <caption>Cancel a subscription</caption>
* const subscription = Rx.Observable.interval(1000).subscribe(
* num => console.log(num),
* undefined,
* () => console.log('completed!') // Will not be called, even
* ); // when cancelling subscription
*
*
* setTimeout(() => {
* subscription.unsubscribe();
* console.log('unsubscribed!');

* // 0 after 1s
