You can use random Math function. If your array has 6 elements. you can use the below JavaScript.

myName[Math.floor(Math.random()*6)]

Why would something simple such as this not work. Up to your to explore the truly "random" aspect of this but likely OK for most things. Note that arrays are 0 based thus the 0,myName.length-1 parameters.

function randomIntFromInterval(min,max)
{
return Math.floor(Math.random()*(max-min+1)+min);
}
var myName = ['Beth', 'Chris', 'Carl', 'April', 'Cinnamon','Ethan'];
var randomName = myName[randomIntFromInterval(0,myName.length-1)];
console.log(randomName);
