The question is more like: "What are the benefits of choosing JavaScript over TypeScript?" You must know that there are pros and cons in every language. There is a reason languages like JS, Python, Zig, C, Go, Rust.. exist.
Given TypeScript is a superset of JavaScript, it's actually a question of "Would you prefer it if we took these (TypeScript) things away?"
I was asking you to take a little distance from the TS-world and use your experience (and maybe emphaty) to look about the pros of JS. Preferrably a list that pleases the TS community. The fact that JS is an "universal language" and runs natively on browsers and Node is a definite one, but then again.. this was a question for you.
