Getting a random value from a JavaScript array

Consider:

var myArray = ['January', 'February', 'March'];

How can I select a random value from this array using JavaScript?

Solution

  • It's a simple one-liner:

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

    For example:

    const months = ["January", "February", "March", "April", "May", "June", "July"];

const random = Math.floor(Math.random() * months.length);
console.log(random, months[random]);
