I've seen several ways of annotating Javascript that IDEs seem to understand. They usually involve using comments before fields, classes, or functions.
The most compliant one seems to be using [JSDoc](https://jsdoc.app/). JSDoc is mostly intended for generating documentation. However, the Typescript compiler can validate types (and can even interoperate with Typescript definitions), if you configure it as such.
In scenarios where you HAVE to write raw Javascript but still would like to do some type validation, this is probably the best solution.

Project mention: Sonos CEO Patrick Spence steps down after app update debacle | news.ycombinator.com | 2025-01-13
I have, it's called Visual Studio Code and I ditched my old native editor(s) for it.
I'd even suggest that the fact that it's JS based has significantly changed the tech world because the editor itself will run in a browser so it's here https://godbolt.org/ , and here https://codesandbox.io, and here https://www.postman.com/, and here https://aws.amazon.com/pm/cloud9/ and 100s or 1000s of other sites.
