Prevent double curly brace notation from displaying momentarily before angular.js compiles/interpolates document
Solution 1:
I think that you are looking for the ngCloak directive: https://docs.angularjs.org/api/ng/directive/ngCloak
From the documentation:
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.
The directive can be applied to the
<body>element, but the preferred usage is to apply multiplengCloakdirectives to small portions of the page to permit progressive rendering of the browser view
Solution 2:
Also, you can use <span ng-bind="hello"></span> instead of {{hello}}.

Solution 3:
To improve the effectiveness of class='ng-cloak' approach when scripts are loaded last, make sure the following css is loaded in the head of the document:
.ng-cloak { display:none; }
