A ∩ B = { x | x ∈ A ∧ x ∈ B }
Допустим, у нас есть две коллекции чисел. Необходимо сравнить эти коллекции и получить общие, встречающиеся в обеих коллекциях, числа:
const num1 = new Set([42, 4, 69, 37, 2])
const num2 = new Set([1, 2, 3, 4])
const inter = num1.intersection(num2)
console.log(inter)
// Set(2) { 2, 4 }

rotate(matrix, "clockwise");
// Would return [[7, 4, 1], [8, 5, 2], [9, 6, 3]]

Поддержка метода isSubsetOf() в основных браузерах и в Node.js появилась в 2024 году. Если попробуете использовать метод в более ранних версиях, это приведёт к ошибке.
