Angular 4 - working with arrays

JavaScript
1

Hello Everybody,

I’m working through a Angular 4 tutorial using HttpClient and having a bit of a problem with displaying data from an array.

The data is from https://jsonplaceholder.typicode.com/posts

I know I can run it through the *ngFor direcitive and this works but I like to know how to go about
select individulal data from the array without receiving an error message: ERROR TypeError: Cannot read property ‘0’ of undefined.

any help you can provide would be greatly appreciated.

example:
{{returnedArray[0][‘body’]}} or {{returnedArray[1][‘body’]}}

component

this._getService.getDetailsMethod().subscribe( 
          data => { this.returnedArray = data;          
          console.log('returnedArray: ', this.returnedArray[0].userId);        
          },

services

getDetailsMethod(){
	return this._httpC.get<any>(this.userListingURL);
  }

PHP

php
if($data) {	
	echo json_encode($data);							
}
