The IDE is not the language.

Racket has good support in VSCode (via magic Racket and the Racket langserver), Emacs (Racket Mode) and Vim. https://download.racket-lang.org/releases/9.0/doc/guide/othe...

The Racket Langserver obviously enables use in other editors that support the LSP. https://github.com/jeapostrophe/racket-langserver For editors that lack LSP support, scheme support is generally sufficient.

All that aside, DrRacket the IDE has some nice features that just don't exist in other editors. I don't know of another IDE that has an integrated macro stepper.
