Angular 5 'inputClick' is declared but its value is never read


Angular 5 'inputClick' is declared but its value is never read

wish of those help Data binding will not happen if you declare it as private. You need to declare it as public to make it available. Follow the code below:
code :
   export class MainInputFormComponent implements OnInit, DoCheck {
      @Output('changeData') sendTheNewDataJSON = new EventEmitter<any>();

      public inputClick: boolean = false;
    }
<input class="born-date-input" formControlName="dateOfBorn" minlength="1" maxlength="10" (click)="inputClick=true"/>
<div class="alert alert-warning" *ngIf="inputClick">
      <small>show warning</small>
</div>

I wish this helpful for you AngularJS is complaining about the missing $resource service. You forgot to include the angular-resource.js file, and to make your main module depend on the ngResource module, as explained in the documentation.

To fix this issue You must surround your typed parameters of an arrow function with parenthesis
code :
validators.forEach((vc:ValidationContext) => {
    vc.validate(value);
});

I wish did fix the issue. The problem will be caused by the scope of "this" being different in your callbacks. JavaScript has a concept of "this" which is unlike most other languages, however typescript (and modern Javascript) has another syntax to work around this, giving you a more intuitive behavior of "this".
code :
this.stompClient.connect(user, password, (frame: any) => this.onConnected(frame));
this.stompClient.subscribe('/topic/public', (message: any) => this.onMessageReceived(message));
this.stompClient.connect(user, password, (frame: any) => {
    console.log('Frame: ' + frame);
    this.stompClient.subscribe('/topic/public', (message: any) => {
        console.log('Message Received from MS: '  +  message);
        try {
            this.messageSubject$.next(message.body);
        } catch (e) {
            console.log('Error: ' + e);
        }
    });
});
