It's different when you're learning on your own and when somebody is teaching you. If you're a company hiring new developers, then you already have people familiar with the language to ramp them up. When we hire new people, we do some pairing, and we do code review on pull requests for features.

I also agree that it's sometimes easier for novices to pick up the language. I've seen students become productive faster than people with a lot of background in imperative style.
