Found a js library with an interesting implementation of getter/setter as one
universal function
x = prop(5)
x() -> 5
x(6) -> 6
x() -> 6
Wondering how one would go about implementing something like this in CLJS
(purely for learning purposes).
Here's the equivalent js:
function prop(store) {
var gs = function() {
if (arguments.length) store = arguments[0];
return store;
};
gs.toJSON = function() {
return store;
};
return gs;
}
I couldn't figure out how to make a closure around a variable in a multi-arity
function. (I'm trying to do this without using the arguments variable, which is
a js-specific hack, and isn't even allowed in strict mode)
(defn prop [store]
(fn ([] store) ([n] (set! store n) store)) ?
