Given a template like this:
<li ng-repeat="user in users">
{{user.firstName}}
</li>
Is there any way to "alias" the "user" so I can do this instead:
<li ng-repeat="SOME MAGIC HERE MAYBE?">
{{firstName}}
</li>
So that I don't need to type the "user." prefix for each expression?

Definition and Usage. The ng-repeat directive repeats a set of HTML, a given number of times. The set of HTML will be repeated once per item in a collection. The collection must be an array or an object. Note: Each instance of the repetition is given its own scope, which consist of the current item.
Note: The $index variable is used to get the Index of the Row created by ng-repeat directive. Each row of the HTML Table consists of a Button which has been assigned ng-click directive. The $index variable is passed as parameter to the GetRowIndex function.
Directives that Create Scopes In most cases, directives and scopes interact but do not create new instances of scope. However, some directives, such as ng-controller and ng-repeat, create new child scopes and attach the child scope to the corresponding DOM element.
$index is a way to show which iteration of a loop you're in. If we set up an ng-repeat to repeat over the letters in 'somewords', like so: <div ng-app="app"> <div ng-repeat="item in 'somewords'.split('')"> {{$index + 1}}. {{item}} </div> </div>
Here is the script to put into controller
$scope.scopify = function(scope, obj){
for (var a in obj) {
scope[a] = obj[a];
}
}
Then call it like this
<li ng-repeat="user in users" ng-init="scopify(this,user)">
{{firstName}}
</li>
