I\'m working on a SF2 application that uses a lot of javascript on the front end.
SF2 provides me a good way of building a nice REST app, manage my database with doc
Searching through the web, I came across different solutions. You can, for example as said before, change the angular symbols. However, I preferred to keep it the most simple as possible by simply telling twig to output the angular symbols:
{{ '{{entity.property}}' }}
