As an experienced dev, I can glance at an API documentation and start coding to use or work with it instantly. But when you take a junior dev, they don't have enough knowledge of basics to comprehend the documentation. E.g let's say the documentation mention concepts like CORS or closure etc, they have to understand those and this only comes from experience over the time. What they are doing, like reading SO and tutorials help them to collaborate in-line with the timeline with experienced devs. As and experienced dev, you can slowly coach them through discussions to develop his overall basic knowledge on a tech or concepts which over the time help him take your approach.
