Passing data to a child component setter in Angular

It is possible to make the data from the parent component go to the setter of a private property. Let's look at an example. Let's say we have a private property with a setter and a getter:

app/user/user.component.tsclass UserComponent {
  private _name: string = '';
  
  set name(name: string) {
    if (name.length < 3) {
      this._name = name;
    } else {
      console.log('error');
    }
  }
  
  get age() {
    return this._userAge;
  }
}

For example, let's make an age setter, in which we will implement the check of the transferred data. We will also make a getter to display the user properties:

app/user/user.component.tsclass UserComponent {
  private _name: string = '';
  
  @Input()
  set name(name: string) {
    if (name.length > 3) {
      this._name = name;
    } else {
      console.log('error');
    }
  }
  
  get name() {
    return this._name;
  }
}

Now let's pass data from the parent component to the child:

app/app.component.html<user-data name="john"></user-data>

And in the child component we will display the passed name on the screen:

app/user/user.component.html<p>{{ name }}</p>
