I can't tell what you mean concretely, because the two examples you give -- gradual typing and lack of concurrently executing threads -- are common to both languages. Python has support for gradual typing, and JavaScript is single-threaded (which is an even stronger property than having a GIL).

As I said, JavaScript was an example, picked because I work it it every day.

There are most certainly better examples, that I am less equipped to present; Rust springs to mind.

Yet whatever example is chosen, the claim remains unchanged: Python experiences the Innovator's Dilemma.
