AngularJS Directives

AngularJS directives are HTML attributes with an ng prefix.
The ng-init directive initializes AngularJS application variables.

<div ng-app="" ng-init="firstName='John'">

<p>The name is <span ng-bind="firstName"></span></p>

</div>

Alternatively with valid HTML:

<div data-ng-app="" data-ng-init="firstName='John'">

<p>The name is <span data-ng-bind="firstName"></span></p>

</div>

You can use data-ng-, instead of ng-, if you want to make your page HTML valid.
