angular.js - How to merge json in angularjs?

Question

Hurry up! ! !
Excuse me, masters, what is the method to merge json in angularjs? Thanks!

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
