Ember.Logger.debug results in double output

[rwjblue]

This means that on a new Ember app using v3.0.0-beta.1 we see the following output for a debug build:

The cause is the boolean logic here:

ember.js/packages/ember-console/lib/index.js

Line 92 in bd7e62f

return console.debug && console.debug(...arguments) || console.info(...arguments); // eslint-disable-line no-console

I believe it should be refactored to:

  debug() {
    if (console.debug) {
      return console.debug(...arguments); // eslint-disable-line no-console
    } else {
      return console.info(...arguments); // eslint-disable-line no-console
    }
  },
