Earlier quoted context omitted.
I would say that TypeScript is actually more popular outside of the .NET ecosystem than in it.
And this is why TypeScript is 1-2% of the market? Check out GitHub and the rest of the community outside of your workplace or whatever place you are seeing this trend, because the numbers are not showing this. Even search terms of google trends http://www.google.com/trends/explore#q=%2Fm%2F02p97%2C%20typ... shows the term JS is more popular than TypeScript. Also look at twitter and what the great developers of JS are…
All of that is wrong.
