0: [object Object]
1: [object Object]
2: [object Object]

Answer 1

try this

angular.forEach(response.data, function(obj){
   console.log(obj.name + ': ' + obj.value);  });

Here name and value will be the key of your Object contains..

Answer 2

I think your data is an array of objects. Try:

angular.forEach(response.data, function(index, item){
   console.log(index + ': ' + item.Objectcourse_name);
});

    });

Answer 4

Your Code absolutely fine, but the problem is with your array data. " is missing against Master of Computer. I have describe you another example below.

course data [Object, Object, Object]
0: Objectcourse_name: "Master of computer" 
1: Objectcourse_name: "Bachelor of Technology"
2: Objectcourse_name: "Master in Technology"
length: 3__proto__: Array[0]

angular.forEach

Invokes the iterator function once for each item in obj collection, which can be either an object or an array.

var obj = {name: 'misko', gender: 'male'};
var log = [];
angular.forEach(obj, function(value, key) {
  console.log(key + ': ' + value);
});
// it will log two iteration like this
// name: misko
// gender: male

You are concatenating strings, not printing an object. Try this:

console.log(key, value)
