Lens Person

Use lenses to update nested records (specific to languages with immutable data).

Updating fields of nested records is kind of annoying in Haskell. One solution is to use lenses. Implement several record accessing functions using lenses, you may use any library you want. The test suite also allows you to avoid lenses alltogether so you can experiment with different approaches.

The Scala exercises assume an SBT project scheme. The exercise solution source should be placed within the exercise directory/src/main/scala. The exercise unit tests can be found within the exercise directory/src/test/scala.

To run the tests simply run the command sbt test in the exercise directory.

For more detailed info about the Scala track see the help page.
