(aset array idx val)
(aset array idx idx2 & idxv)


Sets val at index i in a JavaScript array.

(def a #js [1 2 3])
(aset a 0 "foo")
;;=> #js ["foo" 2 3]

Set nested elements with the additional idxs arguments.

(def a #js [1 2 #js [3 4]])
(aset a 2 0 "foo")
;;=> #js [1 2 #js ["foo" 4]]

For JavaScript objects, use goog.object/set.

(require 'goog.object)
(def obj #js {:foo 1})

(goog.object/set obj "foo" "bar")
;;=> #js {:foo "bar"}
