Associative arrays

//This is an associative array of the results of the student roll call.

//If the value of the key is false, then the student was absent.

var students = {"robert":false,"joe":true,"sharon":true};

//Loop over the students associative array. If the student was present

//output their name to the console

for (var key in students){

if (students[key]===true){

console.log(key);
