function

since v0.0-2411

(js-invoke obj s & args)

Invoke JavaScript object obj method via string s. Needed when the string is not a valid unquoted property name.

If we have a JavaScript object with an unusual property name:

// JavaScript
var obj = {
  "my sum": function(a,b) { return a+b; }
};

We can invoke it from ClojureScript:

(js-invoke js/obj "my sum" 1 2)
;=> 3
