Remove items from an index position

let vegetables = ['Cabbage', 'Turnip', 'Radish', 'Carrot']
console.log(vegetables)
// ["Cabbage", "Turnip", "Radish", "Carrot"]

let pos = 1
let n = 2

let removedItems = vegetables.splice(pos, n)
// this is how to remove items, n defines the number of items to be removed,
// starting at the index position specified by pos and progressing toward the end of array.

console.log(vegetables)
// ["Cabbage", "Carrot"] (the original array is changed)

console.log(removedItems)
// ["Turnip", "Radish"]
