Operators and valueOf with ES6 proxies (Firefox)

I run the following code:

var x = new Proxy({}, {
    get: function(target, name) {
        return target[name];

var y = x + 5;

Why isn’t 'valueOf' printed in console (in Firefox 24)?

  • What is the technical definition of a Javascript iterable and how do you test for it?
  • How come default exports are listed as having multiple branches by `istanbul` code coverage?
  • Correct way to inject pure class into angular 1.x application in ES6
  • Duplicated declarations in compiled out-file using Babel
  • es6 babelify changes variable name, variable can't be found in inspector
  • Flatten arguments into one dimensional array using the rest parameter
  • See http://jsfiddle.net/WFjvv/1/.

    Seems to be fixed in Firefox 26.
