Umm... Instead of proceeding to rewrite the app and author this blog, the author could have realized that JavaScript (or Scala, Java, Python etc.) could realistically be faster than C and should have explained the same to his/her boss.
To be honest, a good attempt by the author but I wouldn't recommend this to a beginner. Why? I don't recommend the use of the native driver - you end up with needlessly complex code.
I don't want to criticize the authors work. He's done a pretty good and thorough job. Hopefully I'll pen down an easier guide later tonight.
