Considering the following 2 approaches:
#1 => controllerOne is injected once
<div ng-controller="controllerOne">
...
{{ fromControllerOne }}
{{ fromControllerOne }}
...
<div ng-controller="controllerTwo">
{{ fromControllerTwo }}
</div>
<div>
{{ fromControllerOne }}
</div>
<!-- more divs -->
...
</div>
#2 => controllerOne is injected twice strictly when it is needed
<div>
...
<span ng-controller="controllerOne">
{{ fromControllerOne }}
{{ fromControllerOne }}
</span>
...
<div ng-controller="controllerTwo">
{{ fromControllerTwo }}
</div>
<div ng-controller="controllerOne">
{{ fromControllerOne }}
</div>
<!-- more divs -->
...
</div>
Questions:
- Which one is better approach? Why?
- Is there any performance hit if the controller is declared multiple
times in a view?
