Step 3: Write Tests

Ensure your changes are covered by tests. Add new test cases or update existing ones to validate your code.

Step 4: Run Tests

Run the test suite to verify that your changes work and don’t break existing functionality:

make test

Step 5: Commit and Push

Commit your changes with a clear, descriptive message and push your branch to your fork:

git add .
git commit -m "Fix issue #123: Correct typo in error message"
git push origin fix-issue-123

Step 6: Open a Pull Request

Go to the Bun GitHub repository and open a pull request (PR). Provide a detailed description of your changes, including:
