Is there a predefind function to check for null, undefined, or blank variables in angularjs? - 


<div  ng-if='documentdata.addresseslist[0] == undefined  ||documentdata.addresseslist[0] == "" || documentdata.addresseslist[0] == null'>      view   </div>

or other way create user defined function checks these 3 condition in once.

you can use function check wether object defined or not (is null or undefined): 

angular.isdefined(value);

https://docs.angularjs.org/api/ng/function/angular.isdefined

according edit, can use 

<div ng-if='documentdata.addresseslist[0]'>view</div>

in view
