TypeScript-da obyektlar ichidagi obyektlar

Obyektlar o‘z ichida alohida interfeyslar bilan tavsiflangan boshqa obyektlarni o‘z ichiga olishi mumkin. Keling, misollar orqali ko‘rib chiqaylik.

Faraz qilaylik, bizda shaharni tavsiflovchi obyekt interfeysi mavjud:

interface City {
	name: string
}

Keling, foydalanuvchini tavsiflovchi interfeysni ham yaratamiz. Bunda foydalanuvchining ismi, yoshi va o‘zi obyekt bo‘lgan shahari bo‘ladi:

interface User {
	name: string,
	age: number,
	city: City
}

Keling, foydalanuvchi bilan obyekt yarataylik:

let city: City = {name: 'london'};
let user: User = {name: 'john', age: 30, city: city};

Shahar uchun alohida o‘zgaruvchi yaratish shart emas:

let user: User = {
	name: 'john',
	age: 30,
	city: {name: 'london'}
};

Quyidagi obyekt berilgan:

let employee {
	name: 'andrew',
	potision: {
		name: 'programmer'
		salary: 1000,
	},
	addr: {
		country: 'belarus',
		city: 'minsk'
	}
};

Ushbu obyektning tuzilishini tavsiflovchi interfeys yarating. Ichki obyektlarni alohida interfeyslarga ajrating.

Quyidagi obyekt berilgan:

let user: User = {
	name: 'john',
	age: 30,
	parents: {
		mother: {
			name: 'jane',
			age: 30,
			parents: null
		},
		father: {
			name: 'eric',
			age: 30,
			parents: null
		}
	}
}
