/**
* There is an ajax operator on the Rx object.
*
* It creates an observable for an Ajax request with either a request object with
* url, headers, etc or a string for a URL.
*
*
* ## Using ajax() to fetch the response object that is being returned from API.
* ```ts
* import { ajax } from 'rxjs/ajax';
* import { map, catchError } from 'rxjs/operators';
* import { of } from 'rxjs';
*
* const obs$ = ajax(`https://api.github.com/users?per_page=5`).pipe(
* map(userResponse => console.log('users: ', userResponse)),
* catchError(error => {
* console.log('error: ', error);
* return of(error);
* })
* );
*
* ```
*
* ## Using ajax.getJSON() to fetch data from API.
* ```ts
* import { ajax } from 'rxjs/ajax';
* import { map, catchError } from 'rxjs/operators';
* import { of } from 'rxjs';
*
* const obs$ = ajax.getJSON(`https://api.github.com/users?per_page=5`).pipe(
* map(userResponse => console.log('users: ', userResponse)),
* catchError(error => {
* console.log('error: ', error);
* return of(error);
* })
* );
*
* ```
*
* ## Using ajax() with object as argument and method POST with a two seconds delay.
* ```ts
* import { ajax } from 'rxjs/ajax';
* import { of } from 'rxjs';
*
* const users = ajax({
* url: 'https://httpbin.org/delay/2',
* method: 'POST',
* headers: {
* 'Content-Type': 'application/json',
* 'rxjs-custom-header': 'Rxjs'
* },
* body: {
* rxjs: 'Hello World!'
* }
* }).pipe(
* map(response => console.log('response: ', response)),
* catchError(error => {
* console.log('error: ', error);
* return of(error);
* })
* );
*
* ```
*
* ## Using ajax() to fetch. An error object that is being returned from the request.
* ```ts
* import { ajax } from 'rxjs/ajax';
* import { map, catchError } from 'rxjs/operators';
* import { of } from 'rxjs';
*
* const obs$ = ajax(`https://api.github.com/404`).pipe(
* map(userResponse => console.log('users: ', userResponse)),
* catchError(error => {
* console.log('error: ', error);
* return of(error);
* })
* );
