GitHub Copilot

GitHub Copilot completes code inside the editor, suggesting the next line or the whole function based on surrounding context and the file you are working in.

It is most effective on repetitive and idiomatic code — boilerplate, tests, data transformations — where the intent is clear from context and the correct implementation is conventional.

Suggestions must be read rather than accepted blindly: it produces confident-looking code that can be subtly wrong, and it will happily follow a mistaken pattern already present in the file.
