Re: [racket-users] Announcing something Kinda FRP-y
I did not even think to extend it that way! What a cool suggestion. Right now I am working on a macro as defined here, since there are times it makes sense to list dependencies explicitly https://github.com/zyrolasting/kinda-ferpy/issues/2 Now if I could get a #-notation to support explicit dependencies without sacrificing too much readability, I'd probably prefer it over all other variants.

Re: [racket-users] Announcing something Kinda FRP-y
Hi Sage, This is pretty cool. With a non-OOP option on the table, I might finally get around to working on an IMGUI-like for Racket. Have you thought about a reader extension to compress the notation? The `stateful-cell` function kinda acts like a box and kinda looks like a `syntax` (or `quote-syntax` w/ kw arg) form, both of which have special #-prefixed notations. Extending the reader to abbreviate `(stateful-cell 1)` and `(stateful-cell (λ _ (+ (x) (y` to, say, #?1 and #?(+ (x) (y)), respectively, could be a fun project.

[racket-users] Re: Running DrRacket on Chromebook
Hi Shu-Hung, I didn't see a response from any chromebook+racket users. Were you able to find a way to run Racket/DrRacket on your Chromebook? I'm not a chromebook user but my limited experience is the linux installer normally works: https://download.racket-lang.org/racket-7-5-x86_64-linux-sh.html If you did get it going I'd be very interested if you had any issues and how you resolved them? (I'd like to add them to the Racket Wiki.)

This is a good (free) course that takes you the lates best practices of JS (getting more functional), react and then react native. https://www.edx.org/course/cs50s-mobile-app-development-with-react-native On Saturday, January 25, 2020 at 6:56:57 PM UTC, 'John Clements' via users-redirect wrote: > > I have a graduate student that wants a self-guided introduction to JS and > React.
