How to add new attributes to objects in angularjs
data is an array of objects obtained from the background. I want to add attributes to value
The code is as follows:

    angular.forEach(data, function(value, key){
        
     });

Answer 1

Use Array.prototype.forEach() directly

var friends=[{name:'Jack',age:16},{name:'John',age:22}];

friends.forEach(function(value,index){
    value.sex='male';
});

console.log(friends);

Answer 2

angular.forEach(data, function(value,  index){
    value.name = "something you like to put here";
});

Answer 3

You can introduce the lodash library and use the _.map method. I often use it in projects for various data operations, which is very convenient. I have to complain about the API provided by the backend staff and make it more friendly. Isn’t that good for everyone?
