What is the best way to randomly choose a string from an array and store it in a variable?

Question

For instance

var names = array["bob","tom","jake"];

Is there a way to choose a random name from the array and then set it as the value of a variable?

var randomName = I'm not sure what code belongs here

Answer 1

Answer №1

It is recommended to utilize the Math.random method for generating random numbers.

var random=Math.floor((Math.random() * names.length));
var randomName=names[random];

Additionally, in javascript, arrays are typically declared as follows:

var names = ["bob","tom","jake"];

Avoid declaring arrays like this :

var names = array["bob","tom","jake"];

var names = ["bob","tom","jake"];
var random=  Math.floor((Math.random() * names.length));
var randomName=names[random];
console.log(randomName);

Answer 3

Implement the random function

 let randomNumber = numbers[Math.floor(Math.random()*elements.length)];

Answer 4

Implement the random function

 let randomNumber = numbers[Math.floor(Math.random()*elements.length)];
