GitHub Copilot is an AI pair programmer that suggests code as you type. It works inside editors like VS Code, and it can complete a line, suggest a whole function, or help you write tests, based on the code and comments around it.

Why beginners like it: it removes the blank-page problem. When you know what you want to build but not the exact syntax, a suggestion gives you a starting point. It is also useful for learning common patterns, like how to fetch data from an API or how to sort a list in a particular language.

How to use it well:

Write a clear comment before you ask for code. For example, "Create a function that takes a list of prices and returns the total after discount" gives Copilot far better context than an empty file.

Take one suggestion at a time. Accept a small block, read it, and run it before moving on. Accepting a whole file at once is how bugs hide.

Always test the suggestion.…
