Angular8

import { Component } from '@angular/core';
@Component({
  selector: 'app-root',
  template: `
  <p>Alive!</p>
  <app-vp-root></app-vp-root>`,
  styleUrls: ['./app.component.css']
})
export class AppComponent {
  someVariable: someType = somevalue 
  someFunction(){
     console.log(this.someVariable)
  }


 ***//can i access through other than this.someVariable line AppComponent.someVariable;***


}

What I have tried:

sometimes there may be situation like using bootbox function in which 'this' does not refers to 'AppComponent' so one must use 'es arrow' function to achieve this so is there any way other than this
