• Irrelevant Suggestions: Sometimes, Copilot might suggest code that doesn't fit your needs. Don't hesitate to edit or ignore these suggestions.

Limitations of GitHub Copilot

While GitHub Copilot is a powerful tool, it's not perfect. Here are some honest limitations:

• Context Understanding: It may not fully understand the context of your project, leading to irrelevant suggestions.
• Code Quality: The quality of generated code can vary. Always review and test the suggestions before implementing them.
• Language Support: While it supports many languages, it might not be as effective for less common ones.

What We Actually Use

In our experience, GitHub Copilot is a fantastic tool for speeding up development, especially for boilerplate code. It works particularly well for JavaScript and Python projects, but we still rely on our own coding skills to ensure quality and context.
