javascript array includes another array

const array1= ["cheese", "dough", "sauce", "pepperoni"]
const array2= ["mozzarella", "peppers", "chicken", "cheese"]

const isIncluded =  array1.some(value => array2.includes(value))
// true

const values = array1.filter(value => array2.includes(value))
// "cheese"
