Disagreed.

The merits of a good static type system becomes evident when you need to write code as part of a large team of developers, the code has to survive in the industry for many years even when the original developer who wrote the code is no longer available, the code has to be part of some significant app, not simply drawing fancy rectangles on screen.

By claiming that TypeScript doesn't add much value over JS, you are practically claiming that every other statically typed language doesn't add much value over Assembly Language.

A type system is analogous to those No-Parking signs on the city roads or the For "Men", For "Women" signs on public Restrooms ( and many other signs and symbols we have in busy cities to guide the traffic and people at public places). Without these signs the people can still operate on the roads and use the restrooms , but imagine the chaos and accident these signs avoid in a busy city. Thats exactly what a good static type system does to a team of many programmers handling a common code base.
