Arrays

1. Isolate

Learn to read, visualize, trace, debug, refactor and write small programs with arrays and no user interactions.

You will explore: different ways of accessing array elements, for-of loops, reference vs. value, copying arrays and side-effects.

2. Practice

Practice using arrays and avoiding side-effects by learning to unit test functions that take arrays as arguments. This includes learning how to test whether or not a function produces array side effects.

1. Write tests for functions that take arrays as arguments.
2. Fix bugs in tested functions that take arrays as arguments.
3. Write functions that take arrays as arguments and do not produce side-effects.

3. Integrate

Integrate the skills from Isolate and Practice into larger programs that use prompt/alert/confirm to interact with the user. You will write and test your functions in a separate folder, and import them to the main program.

1. Import and use functions in your program from a separate file.
2. Write functions that are imported and called in a program.
3. Refactor portions of a program to a separate file as a reusable & tested function.
4. Reverse-engineer programs that use functions declared in a separate file.

see /3-integrate/README.md for more details

4. DOM UI

Looking for a challenge? Try adapting each program from Integrate to use a DOM UI instead of prompt/alert/confirm.
