// An example of getter and setter
class myClass {
	private _x: number;
  
  	get x() {
    	return this._x;
    }
  
 	// in this example we'll try to set _x to only numbers higher than 0
  	set x(value) {
    	if(value <= 0)
          throw new Error('Value cannot be less than 0.');
      	this._x = value;
    }
}
let test = new myClass();
test.x = -1; // You'll be getting an error

class Person {
  private _name: string = ''; // Private property

  // Getter for the name property
  get name(): string {
    return this._name;
  }

  // Setter for the name property
  set name(newName: string) {
    if (newName.length > 0) {
      this._name = newName;
    } else {
      console.error('Name must have at least one character');
    }
  }
}

// Creating an instance of the Person class
const person = new Person();

// Using the setter to set the name
person.name = 'John';

// Using the getter to get the name
console.log(person.name); // Output: John

// Trying to set an empty name (will trigger the error message)
person.name = ''; // Output: Name must have at least one character
