>"What does such and such a library function return?" I'll just say that I usually don't memorize library functions intentionally. I let it happen naturally. If I use a function a lot, it'll get remembered. Usually an IDE/auto-complete module will have that information anyway. C# has spoiled me immensely. That said, you should really promote reviewing the docs for a particular thing after watching a video. Ask them to experiment with this and see if they like it. I think this will help that type of learner cement their knowledge. Use both, not one or the other. The other concern is potential security gotchas which usually aren't covered in videos/tutorials and not mentioned in auto-complete, especially if they are skimming the material to just get work done: they will disengage as soon as their brain gets what it wants from the video. Ask them if they are checking the dates on these things, because it could easily be out-of-date but still stuck high on Google's results.
