There are two sets of data
$scope.c= {"Sedan":{"Toyota":["Camry","Corolla"]},"SUV":{"Jeep":["Wrangler"]}};
var d= {"SUV":{"Ford":["Escape"],"Chevrolet":["Tahoe"]}};
After combining the two sets, I expect to see the following outcome
{"Sedan":{"Toyota":["Camry","Corolla"]},"SUV":{"Jeep":["Wrangler"],"Ford":["Escape"],"Chevrolet":["Tahoe"]}};
