Pattern matching is a fundamental and powerful part of Elixir.
Pattern matching is even used as a replacement for traditional if conditionals. It really can change the way you write code! And it's for the better!
This is a TDD (Test Driven Development) project. Clone the project locally and complete the code to make the tests pass.
Here's a natural progression I recommend.
mix test test/maps_test.exs- Map matchingmix test test/tuples_test.exs- Tuple matchingmix test test/lists_test.exs- List matchingmix test test/structs_test.exs- Struct matchingmix test test/binaries_test.exs- Binary and string matchingmix test test/guard_clauses_test.exs- Guard clauses
Add a code line number while focusing on a specific test. :10
mix test test/maps_test.exs:10
There is a separate solutions branch with examples of how the code can be implemented. Don't peak! Work out your own solutions before looking at other ways to solve it. You learn best by doing.
In order to see the solutions, you should commit your code on the master branch.
git add .
git commit -m "my pattern matching solutions"
Then you can checkout the solutions branch.
git checkout solutions
