I was chatting a new user,@NazCodeland, and they asked: should they separately run ESLint on transpiled JS files if they're already running ESLint with TypeScript-ESLint on source TS files?

The answer isno. The source TS files have all the content of the output JS filesplus type annotations. There's no benefit to also linting the output JS files.

TypeScript-ESLint is "just" a plugin & set of extensions for ESLint. When running ESLint on JS and/or TS source files with TypeScript-ESLint, you're still getting the benefit of all the original ESLint rules.

Thanks for asking great questions@NazCodeland 😁 - we'll add this to the site.
