Accessors in OOP in TypeScript

Just like in pure JavaScript, in TypeScript you can make accessors properties: getters and setters.

In TypeScript, however, accessor names should not match property names. Let's see in practice. Let's make accessors for a private property name. If we also give accessor names name, then the following code will return an error:

class User {
	private name: string = '';
	
	public set name(name: string) { // will give an error this.name = name;
	}
	
	public get name(): string {
		return this.name;
	}
}

Let's fix the problem, for example, by renaming the private property:

class User {
	private _name: string = '';
	
	public set name(name: string) {
		this._name = name;
	}
	
	public get name(): string {
		return this._name;
	}
}

Make a class User containing private properties with name and age. Make accessors of these properties.

Modify the age setter to accept ages between 0 and 120. If any other value is specified, an exception should be thrown.
