Not just one line, but often 3-4 lines, and when writing tests, it often completes 10+ lines for me, and I only have to make a few corrections, sometimes none at all.

You have to read every line and character it suggests, but even so, it saves time.

It has also helped me while learning Typescript. As a beginner, it wasn't/isn't always clear to me how to find the types I need to use in third-party libraries like the Firebase SDK, and generating the code via Copilot and then finding the types it references helps me work backwards to understand where the types are declared. Sometimes, working with Copilot is like having documentation with tailor-made examples. Sometimes it's just wrong, though, so it's a mixed bag.
