map as a filter?

[tve]

Can you provide an example for how to use map as a filter?

The definition of filter in angular is not equivalent to traditional functional programming, it's a way to transform the data representation from view model to the user view.

Assume there is a function in scope called toUpper that does transforming a character to uppercase, then you can use collection|map:toUpper to make the expression be uppercase.
