Having used express, and being shocked at how bad it is, no, express is nowhere near equivalent django/rails (flask, the go to microframework for Python, is more complete than express).

TypeScript has two major issues (which it shares with Python's type annotations): it has to interact with untyped code (so what you think it fine is not, especially when key libraries are not written in TypeScript), and it tends to increase barriers to modifying the code (unlike more functional languages, whose type system tends to be both complete and have less footguns).

As to JavaScript being more commonly used and known, that's dependent on where you're working (especially when it can be sandboxed off so that the majority of users don't need to deal with it, see plotly dash and R-shiny). I suspect having seen multiple examples of systems where JavaScript was used where it was entirely the wrong tool (and where for various reasons Python was the correct one, partially due to the difference in the library ecosystems), we'll see a slow retreat over time of JavaScript to its core areas (being front-end and server-side rendering of the front-end), as more people find that having two languages is a better choice, and rewrite/replace existing JavaScript services.
