Sometimes we need to work with random values, imagine that you have an array of items and you need to get a random value from the array.

We can start creating a function that takes an array of items as a parameter and returns a random item from the array:

function randomItem(items){
  return items[Math.floor(Math.random() * items.length)];

Then we can use the function created above.

let items = [1,200, 'a', 30, 'hello javascript', 50, 56, 20];

randomItem(items) // 'hello javascript'

randomItem(items) // 20

randomItem(items) // 200

Please if you know another way to do this let me know in the comments below ✌️
