title: Object key vs Array key
setup: |
function makeid() {
var text = "";
var possible = "abcdefghijklmnopqrstuvwxyz0123456789";

for (var i = 0; i < 25; i++)
text += possible.charAt(Math.floor(Math.random() * possible.length));

return text;
}

let keys = [];
var array = [];

var object = {};

for (let i =0; i <100; i++) {
let randomString = makeid();
array[randomString] = true;
object[randomString] = true;
keys.push(randomString);
keys.sort();
}
