jshint not respecting template strings

[jakecraige]

It seems jshint isn't respecting the template strings syntax

error:

models/group.js: line 17, col 9, 'activities' is defined but never used.
models/group.js: line 18, col 9, 'guests' is defined but never used.
models/group.js: line 20, col 9, 'activitiesText' is defined but never used.
models/group.js: line 21, col 9, 'guestsText' is defined but never used.
models/group.js: line 29, col 9, 'id' is defined but never used.

offending code:

  summary: Ember.computed('activities.[]', 'guests.[]', function() {
    var activities = this.get('activities.length');
    var guests     = this.get('guests.length');

    var activitiesText = `${activities} ${activities === 1 ? 'Activity' : 'Activities'}`;
    var guestsText     = `${guests} ${guests === 1 ? 'Guest' : 'Guests'}`;

    return `${activitiesText} ${guestsText}`;
  }),

I'm not sure if this is just a jshint setting i need to set or if this addon can somehow fix this but I wanted to bring it up.

Basically, the issue is that JSHint isn't updated to handle all of the various ES6 options.

In ember-cli we are hinting against the actual source in app (which is not processed through esnext filter yet).

I'm thinking we need to allow some plugins to be pre-JSHint (sweet.js and esnext) and others to be post-JSHint (like coffeescript).

Alternatively, we could look into options other than JSHint that may be more aware of ES6 semantics.
