angular.js - angularjs合并json的方法?

Question

加急加急！！！
请问一下大神们，angularjs合并json的方法是那个？谢谢！

Answer 1

angular.merge(obj1, obj2);

Answer 2

angular.extend(dst, src); If the same attribute is used, dst will be overwritten by src

Answer 3

Just to add

res = angular.merge(obj1, obj2);
res = angular.extend(dst, src);
res = Object.assign({}, obj1, obj2);

Both are ok, generally use the first one
