Calling _.flatten on objects about lodash HOT 5 CLOSED

Yap. That is intended.

Lo-Dash is really focused on optimizing for the documented/test/common usage of methods. In the case of flattening objects, Underscore's support is an unintended side effect of their overuse/dependency on _.each.

Thanks for the quick reply.

I just ran into this problem after doing a "drop-in" replacement of underscore with lodash. It would be helpful to post a workaround here... I will if I figure it out before google does.

Ok, easy enough. I had code that looked like this:

    _.chain(FacilityHierarchy.hierarchy).flatten().values().pluck("facility").value()

After a few minutes of investigation I realized that I just needed to call values first (as I should have even with underscore), and it worked fine:

    _.chain(FacilityHierarchy.hierarchy).values().flatten().pluck("facility").value()

Posting it here in case it helps anybody else.

Underscore 1.7.0 no longer supports objects in their _.flatten implementation. For example
_.flatten({name:['abc']}) returns [].
