Every()

Given data:

const items = [
    { name: 'Bike',     price: 100  },
    { name: 'TV',       price: 200  },
    { name: 'Album',    price: 10   },
    { name: 'Book',     price: 5    },
    { name: 'Phone',    price: 500  },
    { name: 'Computer', price: 1000 },
    { name: 'Keyboard', price: 25   }
]

Every method

this method returns a boolean value and is great for asking a question of your data and getting simple response in return. where as some just returns true as soon as it finds a single positive case, every reviews every value and only returns its result after every value has passed its check.

---

const hasExpensiveItems = items.every((item) => {
    return item.price <= 100
})

Result:

false

for each item in items, iare all items less than or equal to 100? if so return true, otherwise false.
