Please re-read the GP carefully: "The primary reason for this is because the people writing JavaScript do not know what they are doing".

If that isn't a personal attack on a particular group of developers, then I'm not sure what constitutes personal attacks.

Also, as a top-flight engineer working in a multi-billion company (and also having worked with Java and .net professionally for many years), the JS/TS ecosystem as a whole has never been better than it is today.

And TS remains my lang of choice today, for professional and personal projects :)
