Make a base SuperHero class. Give it some properties, and actions (methods) that change those properties.

Make at least one of the methods interact with another SuperHero, such as attack() or giveMotivationalSpeech().

Add tests for your SuperHero class.

1. Write tests for what it should do in tests.js.
2. Open index.html to run the tests.

Make 2+ SuperHero subclasses that have two or special properties and actions, with tests covering all of the functionality, using test-driven development (TDD).

1. Write a test for what it should do in tests.js.
2. Open index.html to run the tests.
3. Define the class in super_hero.js, and make the tests pass.
4. Repeat from step 1.
