A few JavaScript One-Liners

one-liners.js

// taken from https://medium.com/html5-css3/7c80a4b731f8
// and expanded, unreadable one-liners are kind of pointless

//pad zeroes
function pad(num) {
    return ('0' + num).split('').reverse().splice(0,2).reverse().join('')
}

// get page query params
var qp = document.location.search.replace(/(^\?)/,'')
    .split("&").map( function (n) {
        return n=n.split('='), this[n[0]]=n[1], this;
    }.bind({}))[0];

// my own
// return random member of array
rand = function (array) {
            return array[Math.floor(Math.random() * array.length)];
        }
