Class exercise

• Create an array with list of values
• Change the last element to any
• If we insert some item in between, still it should apply the change

for example

let arr = ["lion", "tiger", "bear", "wolf", "fox"]

// change the last element from `fox` to `dog`
// code here

console.log(arr)
// ["lion", "tiger", "bear", "wolf", "dog"]
