Best Coding Practices

Helpful for Beginners!

Here are some foundational coding practices I've picked up that have made a real difference in how I write and maintain code.

Code Editor

Visual Studio Code is my go-to. Syntax highlighting, code-completions, built-in Git integration, and a massive plugin ecosystem for debugging and linting make it hard to beat.

GitHub Workflow

Version control with Git is non-negotiable. Beyond just committing code, explore:

• GitHub Marketplace: integrations for testing, CI/CD, and linting
• GitHub Projects: task tracking and team collaboration
• GitHub Workflows: automate repetitive tasks with YAML-based scripts

Virtual Environments

Always maintain separate project environments. Dependency conflicts are a nightmare. I use VirtualEnv to isolate each project's dependencies from the base system environment. This keeps things clean and reproducible.

Debugging

Two approaches I rely on:

1. Process of Elimination: revert to known working code, then add changes incrementally with print statements to narrow down the issue
2. Test-Driven Development: write tests before implementation. When something breaks, the tests tell you exactly where. This practice becomes even more powerful when AI agents write your code

Finding Error Solutions

When you hit an error: copy the exact error message and code. Search Stack Overflow, GitHub Issues, and official documentation. Avoid unreliable sources that may lead you down the wrong path.

Documentation

Good documentation includes:

• Inline comments for complex logic
• README files explaining purpose, setup, and usage
• GitHub Pages for larger projects that need proper documentation sites

Adopt these habits early. Future you will be grateful.
