I really enjoy writing JS/TS - I find that eg arrow functions mixed with React allow for really concise and expressive solutions. You are correct about the ecosystem... maybe not per se, but that supply chain attacks are hopelessly intractable at the moment. How could you possibly go about writing a modern SPA that notionally cares about security when the third party software you must rely on is impossible to verify? I would love if browsers let you run JS in a sand boxed mode wherein you could just pass a bundle of vendored upstream software without the ability to touch the window, network, global state, etc.
