here about.component.ts ` import{ Component } from '@angular/core'; import { FormControl } from '@angular/forms';

@Component({ selector:"about-page", templateUrl: 'app/about/about.component.html' })

export class AboutComponent{

public Firstname: FormControl = new FormControl("");
public Lastname: FormControl = new FormControl("");
public Email: FormControl = new FormControl("");
public Address: FormControl = new FormControl("");
constructor() {}

} about.component.html
