AngularJS - Hiding value based on null and empty array

Question

I am trying to perform an ng-hide when a value is either null or an empty array (in Firebug, this appears as []).

I can carry out the null via:

ng-hide="myData.Address == null"

However when i try:

ng-hide="myData.Address == null || myData.Address == []"

The value still appears.

Try this:

ng-hide="myData.Address == null || myData.Address.length == 0"

null and [] are both false, a shorter and cleaner way

ng-show="myData.Address"

Not true, `[]` is not falsy: https://developer.mozilla.org/en-US/docs/Glossary/Falsy – bumbur Mar 23 '20 at 22:54
