Convert a phrase to its acronym.
Techies love their TLA (Three Letter Acronyms)!
Help generate some jargon by writing a program that converts a long name like Portable Network Graphics to its acronym (PNG).
Refer to the Installing Elm page for information about installing elm.
The code you have to write is located inside the
src/ directory of the exercise.
Elm automatically installs packages dependencies the first time you run the tests
so we can start by running the tests from the exercise directory with:
To automatically run tests again when you save changes:
$ elm-test --watch
As you work your way through the tests suite in the file
be sure to remove the
calls from each test until you get them all passing!

A huge amount can be learned from reading other people’s code. This is why we wanted to give exercism users the option of making their solutions public.
Here are some questions to help you reflect on this solution and learn the most from it.
