A new `is-empty` helper should be added about ember-truth-helpers HOT 7 CLOSED

I think adding is-empty seems fine, but I'm not convinced that truthConvert should be changed. Frankly, the idea that this isn't how JS works doesn't really hold much sway to me. HBS is not JS, and Ember fundamentally considers empty arrays as falsey in HBS.

It would be nice if this also checked for empty objects {}

Ember.isEmpty returns false when checking {} so I had to create a helper that checked the length of my object's key length. eg., Object.keys(myObject).length === 0 returns true.

or maybe it's better to create a new helper is-empty-object

+1 @rwjblue What's the alternative right now for composing empty checks with the other truth helpers?

@adjohnson916 If you know you always have an array (even empty) {{unless myArray.length}} if not, you'll have to chain a check for the array {{if (and myArray myArray.length)

@rwjblue @btecu I've answered my own question about how to handle this currently by adding new unit tests in #27.

I want to pick this up and add it if somebody is not already working on it.

👍 on the is-empty using Ember.isEmpty(). I would look into it myself, but haven't done anything with addons quite yet. :-)
