Use javascript filter to retrieve objects, please find below code snippet:

var heroes = [
{name: 'Batman', franchise: 'DC'},
{name: 'Ironman', franchise: 'Marvel'},
{name: 'Thor', franchise: 'Marvel'},
{name: 'Superman', franchise: 'DC'}
];

var marvelHeroes =  heroes.filter(function(hero) {
 return hero.franchise == 'Marvel';
});
console.log(marvelHeroes);
