[AngularJS] Angular 9 with HTTP use?

[Sampath Tharanga]

Hi,

I'm a beginner with Angular9. So, I need to display data with coming to 
HTTP url(GET API link). Please help me to solve this problem.

Here my code, It's wrong. Help me to solve this.

import { Component, OnInit } from '@angular/core';
import { HttpClient } from '@angular/common/http';
import { Observable, throwError } from 'rxjs';
import { map, catchError} from 'rxjs/operators';

interface Course {
    description: string;
    courseListIcon:string;
    iconUrl:string;
    longDescription:string;
    url:string;
}

@Component({
  selector: 'my-app',
  templateUrl: './app.component.html',
  styleUrls: [ './app.component.css' ]
})

export class AppComponent {
    courses$: Observable<Course[]>;

    constructor(private http:HttpClient) {
    }

    ngOnInit() {
        this.courses$ = this.http
            .get<Course[]>("https://xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx";) 
// HERE URL
            .map(data => _.values(data))
            .do(console.log);
    }
}
