`or` doesn't work the same way as `||` in JavaScript about ember-truth-helpers HOT 3 CLOSED

I much prefer the behavior it is using now. It aligns with how Ember templates treat empty arrays. Changing it will make it behave different then how Ember handles empty arrays.

{{#each (array) as |item|}}
  This never is handled
{{else}}
  This is handled as the items are empty
{{/each}}

{{#if (array)}}
  Never gets called
{{else}}
  Treated as falsey 'cause the array is empty
{{/if}}

{{if (array) "Not shown" "shown because falsey"}}

Well, I guess that's a matter of taste. I personally would prefer to have the same behavior in JS and in HBS for similar things - so if ([]) ... to behave the same as {{if (array) ...}}. each is a bit different as it doesn't have a direct equivalent in JS (I mean the else part of course) - so I agree that the current behavior is OK. But for the if examples I think that's confusing to people. Besides, you could just write {{if someArray.length ...}} and that would work the way you want.

So after a nice discussion I'll close the issue as ember-truth-helpers does the correct thing according to the RFC (even though the RFC says that ember-truth-helpers does something else - the RFC is wrong in this case).
