I am try to convert a JavaScript array to an array of Object like

class Person {
    name: string ="Test";
    age: number = 23;
    
    get Name(): string{
        return this.name;
    }
} 
const getPerson =():Array<Person> =>{
    var d:Array<Person> = [{"name": "Hugo", "age": 25},{"name": "Test", "age": 23}] as Person[];
  return  d;
}

console.log( getPerson()[0] instanceof Person)

console.log( getPerson()[0].Name)
console.log( getPerson()[1].Name)

But the output says, that the entries in the array are not instance of Person

[LOG]: false 
[LOG]: undefined 
[LOG]: undefined 

I expect the output

[LOG]: true
[LOG]: Hugo
[LOG]: Test

Can someone explain why this is the case and what I have to change, that it works?
