Javascript how to find option values in object loop -


i have following objects in javascript:

var group = {         'object1': {             option1: '',             option2: false         },         'object2': {             option1: '',             option2: true         },         'object3': {             option1: '',             option2: true         }     };

how can loop through group in order find every object has option2 of true?

for example, giving me array of ['object2', 'object3']

var group = {     'object1': {         option1: '',         option2: false     },     'object2': {         option1: '',         option2: true     },     'object3': {         option1: '',         option2: true     } };  var filtered = [];  (var in group){     if (group[i].option2 === true){         filtered.push(i);     } }  // filtered ['object2', 'object3']
