js get random number from array

//get random value from array
var colors = ["red","blue","green","yellow"];
var randColor = colors[Math.floor(Math.random() * colors.length)];

var colors = ["red","blue","green","yellow"];
var randomColor = colors[Math.floor(Math.random()*colors.length)]; //pluck a random color

var items = ['Yes', 'No', 'Maybe'];
var item = items[Math.floor(Math.random() * items.length)];

const months = ["January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"];
const randomMonth = months[Math.floor(Math.random() * months.length)];

console.log("random month =>", randomMonth);

const randomElement = array[Math.floor(Math.random() * array.length)];

var item = items[Math.floor(Math.random() * items.length)];

let items = [12, 548 , 'a' , 2 , 5478 , 'foo' , 8852, , 'Doe' , 2145 , 119];

let  randomItem = items[Math.floor(Math.random() * items.length)];

array.sort(() => Math.random() - Math.random()).slice(0, n)

 const arr = myArray
      .map((a) => ({sort: Math.random(), value: a}))
      .sort((a, b) => a.sort - b.sort)
      .map((a) => a.value)
