/** | 
						|
 * 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( | 
						|

						|
 *   catchError(error => { | 
						|
 *     console.log('error: ', error); | 
						|
 *     return of(error); | 
						|
