I am a TypeScript fan but I do acknowledge the existence of the tax. TS is another cog in the machine that does useful work but can sometimes confusingly interact with other cogs (e.g. miles long unreadable TS errors coming out of React). Using or not using TS is not a trivial decision to me and should be made with consideration to the complexity of your stack.

Can relate about illegible React stack traces in production builds. One of the reasons in my case was Create-React-App obfuscating ES6 class names, which is just insane! Just why???! Why throw all code structure away just to save a couple KBs. The worst part is CRA folks acting like dictators when asked to provide an option to toggle that: "Why in heavens earth would you need that?". "You can fork our 30K+ line repo [just to toggle minification] if you want".

Sorry for the off topic rant!

P.S: Yes I know source maps exist. They suck/aren't reliable.

You could also use customize-cra and skip on minifications in about 10 lines of code

I don't believe whether or not using TS has to do with the rest of your stack, but more about data consistency and the like.

I for one am building a large CRUD application with dozens of models spanning hundreds of fields, and Typescript is helping me (though not a panacea) keeping things correct.

I'm comparing it to a project I did years ago, first Backbone, then Angular, but both before 'typesave JS' was a thing, and that one relied heavily on reading and comparing keys and a deep knowledge of the domain.

But nearly ten years later, I don't have the mental capacity for that anymore and I need the crutches that typed languages offer me. By crutches I mean securities, safeguards and IDE assistance.

It makes sense for anything nontrivial IMO. Types allow you to be able to free up mental space. You can trust the type checker instead of having to rely on your own abilities.
