Avoiding to show the html angular tags when loading AngularJS app

Question

I'm a newbie in Angular JS(I'm using #1.5.8)and I'm following the docs.angularjs.org/tutorial tutorials.

I've the html

<div class="jumbotron">
        <h1>{{application_name | uppercase }}</h1>
        <p class="lead" >
   </div>

where is set in main.js

$scope.application_name='app';

everything is going well, but every time I reload manually(refresh localhost page) or with gulp, the page renders earlier the html,the user sees application_name printed in big and after is rendered with the wanted value.
My question is :
is there a way to avoid showing Angular js expressions when rendering the page for first time?
I want that when I go to the localhost page, the page shows app and not application_name

writing it like '<h1 ng-cloak="application_name | uppercase"></h1> <p class="lead" >' I still see the angular expression, ng-bind works instead — Fedeco

@FedericoNastasi please see my answer... in my opinion ng-bind is best but ngcloak works... you are not suppose to use it like ng-cloak="application_name | uppercase".... you would use brackets. — defaultcheckbox

You can avoid it by not using brackets...

<div class="jumbotron">
        <h1 ng-bind="application_name | uppercase"></h1>
        <p class="lead" >
   </div>

As Stephen C commented above you can also use ngcloak..

<div class="jumbotron" ng-cloak>
        <h1>{{ application_name | uppercase }}</h1>
        <p class="lead" >
</div>

Here is a great link about the difference between cloak and bind. Differences between ng-bind and ng-cloak in angularjs

In summary, directly from that link:

ngBind

The ngBind attribute tells Angular to replace the text content of the specified HTML element with the value of a given expression, and to update the text content when the value of that expression changes.

ngCloak

The ngCloak directive is used to prevent the Angular html template from being briefly displayed by the browser in its raw (uncompiled) form while your application is loading. Use this directive to avoid the undesirable flicker effect caused by the html template display.

Use ng-bind , this will show only value after parsing.

<div class="jumbotron">
     <h1 ng-bind="application_name | uppercase"></h1>
     <p class="lead" >
</div>

You should use ng-bind when you can => When you dont need a two-way binding but a one-way only.

The ngBind attribute tells Angular to replace the text content of the specified HTML element with the value of a given expression, and to update the text content when the value of that expression changes.

You can also use ng-cloack
