How can I do something like var count = seen[input]; in sibilant?
whats the best way to embed js functions inside a sibilant (lisp) file?
those would be slightly different. In general, it’s probably preferable to keep the language boundaries between files, using the require system
so if you have some js you want to use from within sibilant, save it as a .js file and require it
or just require
anything you use in javascript. sibilant was/is a tool for writing javascript, and doesn’t impose any constraints on that. it hasn’t been updated for modern js, but that doesn’t limit the use of any particular data structures
Anybody know how to append element to an array now that "append" is deprecated?
To append, you can use any of the array prototype methods you’d use in normal js, like push and pop and shift and unshift
Or ... if you’re looking to expand an array into an array literal
Do I need to add any configuration to use them?
Well, with two 3s because I’m an idiot
I’d need to see how you’re calling push. There’s no confirmation needed
Do you have an array in a variable and want to add something new to it, or are you constructing a literal array and want to expand another array into it?
(var starts [])
(each-key task pre
(if (= 0 (get pre task))
(push starts task)
)
)
I have an empty array - starts
.push works!
Thank you so much @jbr
Howdy, I have an array of objects and would like to simply loop thru and check if the array in the object that is in the array is empty. an example of what my array of objects may look like:
;;[{a 'helloa', b ["hellob"]}] . I'm getting an error TypeError: (intermediate value).call(...) is not a function and was hoping for some advice
(def myfunc (objs)
(each obj objs (
(if
(empty? obj.b)
(do
(console.log "b is empty"))
)
)
)
)
