Been chasing a bug this morning which turned out to revolve around using Big.js
for BigDecs in my re-frame app.
Big.js has a synonym for add()--plus()--which worked fine in my dev compilation
mode of :none. For production compilation with :advanced, my reduce function
was blowing up.
Here's how add() and plus() are declared in Big.js:
P.add = P.plus = function (y) {....}
In :none plus() was seen as a defined method, but in :advanced it was not, so
an "undefined" error was reported.
Once I changed to use add(), my reduce function worked as expected.
;; works in :none, fails in :advanced
(reduce (fn [a b] (.plus a b)) (js/Big "0") (map :concentration chems))
;; works in both
(reduce (fn [a b] (.add a b)) (js/Big "0") (map :concentration chems))
Curious about others thoughts on this.
Cheers,
Jamie
