This code runs, but I'm guessing that its not the "right way" to do it.
(define (js-date [i (current-date)])
(let ([original-format (date-display-format)]
[return ((λ ()
(date-display-format 'rfc2822)
(date->string i #t)))])
(date-display-format original-format)
return))
1) In "some other language" using a function as the default value for an
argument is inefficient and frowned upon. Is that the case in racket?
2) I want to set the date-format back to whatever it was before the
function ran, so (date-display-format original-format) seems like it
should go last, but I need my return value... What I have looks hacky,
whats the "correct" way to do it?
Thanks!
Jordan
