Agreed but that does not contradict anything I wrote.

There is a confusion on terminology though. You are arguing about ease of use which is a different measure from complexity. That might have caused a misunderstanding.

Complexity is an objective measure while ease of use is subjective and based on your previous experience. For example the language Brainfuck is very simple (conceptually) but very difficult to use for most humans.

TS is objectively complex but also easier to use for Ruby/JS devs as you wrote.
