So I have implemented a script that uses angular as well, however when I use {{1+1}} it does nothing, also it shows me a warning that is created inside the Javascript file(we created it too show that it works).
The code for the lightning static resource is:
<aura:component implements="flexipage:availableForAllPageTypes">
<ltng:require
styles="/resource/bootstrap"
scripts="/resource/BookingWidget"
/>
<html ng-app="">
<body >
{{1+1}}
</body>
</html>
ng-app="" even being empty it should run {{1+1}}
I left it for five minutes and it gave me a warning
"WARNING: Tried to load angular more than once"
<html>
tag needs a closing pointed bracket -<html ng-app="">
. If it is closed in your code, please update this excerpt.
