Differences between Success and Then Angularjs

So far I’ve been using the success to the Http Promises.

Ex:

$http.get(/url).success(function(data){
     console.log("Sucesso");
    })
    .error(function(response, status) {
      console.log("erro " + status);
    });
  }

But today I found an example where the success may be replaced by then:

$http.get(/url).then(function successCallback(response) {
    console.log("Sucesso");
  }, function errorCallback(response) {
    console.log("Erro: "+response);
  });

I would like to know the differences between these two promisses and what are the advantages of using them.

The methods success and error are the old way to process Promises for the success and error cases resulting from preview $http.

They do the same thing as the method then() and its two parameters of callback.

In addition, the methods Success and error are now marked as deprecated:

The $http legacy Promise methods Success and error have been deprecated. Use the standard then method Instead. If $httpProvider.useLegacyPromiseExtensions is set to false then These methods will throw $http/legacy error.

Therefore use then(), or write direct callbacks.
