# Isogram Determine if a word or phrase is an isogram. An isogram (also known as a "nonpattern word") is a word or phrase without a repeating letter, however spaces and hyphens are allowed to appear multiple times. Examples of isograms: - lumberjacks - background - downstream - six-year-old The word *isograms*, however, is not an isogram, because the s repeats. ## Setup Go through the setup instructions for JavaScript to install the necessary dependencies: http://exercism.io/languages/javascript/installation ## Running the test suite The provided test suite uses [Jasmine](https://jasmine.github.io/). You can install it by opening a terminal window and running the following command: ```sh npm install -g jasmine ``` Run the test suite from the exercise directory with: ```sh jasmine isogram.spec.js ``` In many test suites all but the first test have been marked "pending". Once you get a test passing, activate the next one by changing `xit` to `it`. ## Source Wikipedia [https://en.wikipedia.org/wiki/Isogram](https://en.wikipedia.org/wiki/Isogram) ## Submitting Incomplete Solutions It's possible to submit an incomplete solution so you can see how others have completed the exercise.
