Should I move up to typescript from vanilla Js for mostly framework-web?

what kind of situation are we talking here? are you alone or in a team, how big and complex is your project, did you ever use typescript? you know... use the right tool for the job 🙂

Short answer: Yes

Well, it depends. If your site is one or two small ish JS files and you're the only one working on it. Leave it. If however you are in a team, working with big sites or critical stuff, Typescript is definitely the way to go.

I despise js although appreciate it more using ts but I’m used to strongly typed languages so biased, it’s not hard to pick up, it has an any type so it’s easy to migrate code and add typings later

Yes.
