Assuming that you have only properties and not any functions in your object, you can just use:

var newObject = JSON.parse(JSON.stringify(oldObject));

//Using JSON stringify function
var obj2 = JSON.parse(JSON.stringify(obj));

//Using lodash deep clone method
var obj2 = _.cloneDeep(obj, true);

//Angular framework comes with angular.copy function
var obj2 = angular.copy(obj);

// Using jQuery extend function
var obj2 = $.extend(true, {}, obj);
