@alien4u Its really whatever you wanna develop in that works for you. The downside to it is the majority of the community isn't going to be of much help w/ TS specifically but the NetSuite side shouldn't matter. Me personally, i'll never use it (unless i'm forced to) but that doesn't mean someone else can't.. people still use notepad++/sublime text/eclipse to do all their development in as well (maybe some vim people?). If you're productive and efficient who cares? Just don't expect help w/ it since its not the "norm" right now
