I know you can't get friends of friends, but can you get mutual friends using some query, in a computationally efficient manner?
Could I even iterate through my friends to see which of them is friends with a target? Is there any good way to get Mutual friends?
You can do it like this:
This will return the id of the mutual friends. Hope this helps you :)
EDIT:
If you want to get the mutual friends between you and id=13245 then you can do like:
It will return all mutual friends id.
Hope this gives you what you want.
