ng-cloak is your friend..
The worst part is many default values could be displayed but now we're hiding sometimes large junks when for the best UX you should show as much of the page as possible.
Ultimately just not a fan of any template engine that relies on being fast enough to hide and replace values in the raw HTML.
<p ng-bind="value"></p>
instead of
<p>{{value}}</p>
It is preferable to use ngBind instead of {{ expression }} if a template is momentarily displayed by the browser in its raw state before Angular compiles it. Since ngBind is an element attribute, it makes the bindings invisible to the user while the page is loading.
