CODE CHALLENGES 👨🏻‍💻

PURPOSE

This repository is a collection of completed code challenges, katas, whiteboarding question practice, and other assorted problems from a variety of places.

A good general place to start is this list of 14 techniques that are good to know for interviews.

BUILT WITH

• The code challenge solutions use JavaScript, Java, Python, and Solidity
• The JavaScript tests are written with Facebook's Jest for unit testing, while Python uses its built-in unittest. Java and Solidity tests are coming soon.

GETTING STARTED

1. Fork or clone this repository to your local machine

2. For JavaScript challenges:

   • Open your terminal and install Jest using yarn global add jest
   • Navigate to the parent directory and run Jest by entering the command jest --watch
   • Select which method of testing in Jest you want to use via the command line prompts

3. For Python challenges:

   • Open your terminal and install dependencies via poetry install
   • Start a shell environment by running either poetry shell
   • Run tests locally by identifying the subdirectory you want to run and using the command PYTHONPATH=$(pwd) poetry run python ./src/path/to/the/test_file.py to run it

4. Modify some of the code in a test file to watch the magic happen
