Here is an Angular component code snippet:
export class ListComponent implements OnInit {
showComments: boolean = false;
posts$: Observable<PostModel[]>;
constructor(private postService: PostService) { }
ngOnInit() {
this.posts$ = this.getPosts();
}
getPosts(): Observable<PostModel[]> {
return this.postService.getRecentPosts();
}
}
Is it necessary to define posts$ within the constructor?
What should be the default value for showComments? Is it acceptable to define it inside ngOnInit as well?
If not, when is the appropriate time to use the ngOnInit method?
