Not sure how's that relevant.

Any valid JavaScript is valid TypeScript and you're gonna write and read TS anyway in the industry.

They aren't in competition, but coming back to the first comment it sounds reasonable to start directly with TS for many users.

Your experience is not the industry. JS is widely used, almost certainly more than TS.

My experience may not, but the annual JS dev survey points that TS is the main way to write JS from years.

and not to mention terrible.
