Reactda ob'ektlar massivini chiqarish

Faraz qilaylik, bizda mahsulotlar bilan ob'ektlar massivi mavjud:

const prods = [
	{name: 'product1', cost: 100},
	{name: 'product2', cost: 200},
	{name: 'product3', cost: 300},
];

function App() {
	
}

Keling, har bir mahsulotni o'z abzasida chiqaramiz:

function App() {
	const res = prods.map(function(item) {
		return <p>{item.name} {item.cost}</p>;
	});
	
	return <div>
		{res}
	</div>;
}

Mahsulot nomi va narxini alohida tegga joylash mumkin, masalan, shu tarzda:

function App() {
	const res = prods.map(function(item) {
		return <p>
			<span>{item.name}</span>:
			<span>{item.cost}</span>
		</p>;
	});
	
	return <div>
		{res}
	</div>;
}

key atributini qo'shishni unutmang:

function App() {
	const res = prods.map(function(item, index) {
		return <p key={index}>
			<span>{item.name}</span>:
			<span>{item.cost}</span>
		</p>;
	});
	
	return <div>
		{res}
	</div>;
}

App komponentida quyidagi massiv berilgan:

const users = [
	{name: 'user1', surn: 'surn1', age: 30},
	{name: 'user2', surn: 'surn2', age: 31},
	{name: 'user3', surn: 'surn3', age: 32},
];

Ushbu massiv elementlarini ul ro'yxat ko'rinishida chiqaring.
