/**
|
||||
* Convert an object into an Observable of `[key, value]` pairs.
|
||||
*
|
||||
* <span class="informal">Turn entries of an object into a stream.</span>
|
||||
*
|
||||
* <img src="./img/pairs.png" width="100%">
|
||||
*
|
||||
* `pairs` takes an arbitrary object and returns an Observable that emits arrays. Each
|
||||
* emitted array has exactly two elements - the first is a key from the object
|
||||
* and the second is a value corresponding to that key. Keys are extracted from
|
||||
* an object via `Object.keys` function, which means that they will be only
|
||||
* enumerable keys that are present on an object directly - not ones inherited
|
||||
* via prototype chain.
|
||||
*
|
||||
* By default these arrays are emitted synchronously. To change that you can
|
||||
* pass a {@link SchedulerLike} as a second argument to `pairs`.
|
||||
*
|
||||
* @example <caption>Converts a javascript object to an Observable</caption>
|
||||
* ```ts
|
||||
* import { pairs } from 'rxjs';
|
||||
*
|
||||
* const obj = {
|
||||
* foo: 42,
|
||||
* bar: 56,
|
||||
* baz: 78
|
||||
* };
|
||||
*
|
||||
* pairs(obj)
|
||||
* .subscribe(
|
||||
* value => console.log(value),
|
||||
* err => {},
|
||||
* () => console.log('the end!')
|
||||
* );
|
||||
*
|
||||
* // Logs:
|
||||
* // ["foo", 42],
|
||||
* // ["bar", 56],
|
||||
* // ["baz", 78],
|
||||
* // "the end!"
|
||||
* ```
|
||||
*
|
||||
* @param {Object} obj The object to inspect and turn into an
|
||||
* Observable sequence.
|
||||
* @param {Scheduler} [scheduler] An optional IScheduler to schedule
|
||||
* when resulting Observable will emit values.
|
||||
* @returns {(Observable<Array<string|T>>)} An observable sequence of
|
||||
* [key, value] pairs from the object.
