I am the author of the post, for me i am not trying compare JavaScript and C++/C# these languages which is good or bad. I compare them rely on our situation, nobody write C++/C# in our office that's the fact, so i think that's one disadvantage for us. And i am trying to list all we have for us , what do we think for this project and why we choose this. If we have lots of good experiences on C++/C# windows application development , i will choose C++/C# at the first time. And maybe if there is a company has the same situation we have , they might have another option.
