Get a random item from a JavaScript array

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

var randomArray = [

   '#cc0000','#00cc00', '#0000cc'

];



// use _.sample

var randomElement = _.sample(randomArray);



// manually use _.random

var randomElement = randomArray[_.random(randomArray.length-1)];

// use underscore's shuffle function

var firstRandomElement = _.shuffle(randomArray)[0];
