You can use css - nth-child:

This is a really bad idea, especially if that function is named correctly. You have zero control over how many times that function is going to be called (and it’s going to be a ton of times, so it’s a bad idea for performance reasons even if the function itself is idempotent).

Don’t call functions from inside {{}} interpolation expressions. Just put properties in there.
