JavaScript Program to Get Random Item From an Array

To understand this example, you should have the knowledge of the following JavaScript programming topics:

Example: Get Random Item From an Array

// program to get a random item from an array

function getRandomItem(arr) {

    // get random index value
    const randomIndex = Math.floor(Math.random() * arr.length);

    // get random item
    const item = arr[randomIndex];

    return item;

const array = [1, 'hello', 5, 8];

const result = getRandomItem(array);



In the above program, a random item from an array is accessed.

  • A random number between 0 to array.length is generated using the Math.random() method.
  • The Math.floor() returns the nearest integer value generated by Math.random().
  • This random index is then used to access a random array element.
