I both agree and disagree with this. I think if you're coming from a statically typed language, and you're familiar with features in those language - Typescript is a very complex type system, where it can often be difficult or frustrating to express common paradigms.

That said... if you're coming from something like Ruby/JS, typescript has a pretty simple path to convert your existing code, and it doesn't get too fussy about letting you punt on the problem for a bit (start with very loose rules and lots of "any" - get more strict over time).

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.
