🚀 Usage

Running Examples

JavaScript:

node algorithm/bubble-sort.js
node patterns/creational/singleton.js
node paradigms/functional.js

Python:

python algorithm/bubble-sort.py
python patterns/creational/singleton.py
python paradigms/functional.py

Runner (list + run)

You can also use the repo runner to list examples and run them by path or index.

python run.py list --lang py --limit 20
python run.py list --contains authentication

python run.py run algorithm/bubble-sort.py
python run.py run web-development/authentication.js
python run.py run 1
python run.py run authentication --lang js

🧹 Linting & Formatting

Repo-wide lint/format tooling is included for both Python and JavaScript.

Python (Ruff):

python -m pip install -r requirements-dev.txt
ruff format .
ruff check .

JavaScript (Prettier + ESLint):

npm install
npm run format:js
npm run lint:js

Run both:

npm run format
npm run lint

Git hooks (pre-commit + pre-push)

This repo includes optional Git hooks to auto-format/lint on commit and run check-only validation on push.

python -m pip install -r requirements-dev.txt
npm install

pre-commit install
pre-commit install --hook-type pre-push

# optional: run across the whole repo
pre-commit run --all-files
