Google Translate API - isReliable not returning anything

Question

Has someone ever used isReliable with the Google Translate API? It always returns "undefined" value.

google.language.translate('hello','','es',function(result){
    alert(result.isReliable); // prints undefined
    alert(result.translation); // prints "hola"
});

Answer 1

isReliable - A boolean representing whether or not the detection interval believes the language code is reliable for the given text.

It only works for language detection (not for translation).
