To be honest, I would treat them as a wishlist. If you've got a solid handle on at least some of the requirements, it literally won't hurt to apply.

More often than not, those job requirements are not written by the person who is doing the hiring, or the people you will be working with. Just be honest about what you know, what areas you are willing to grow in, and what excites you about the job position.

Some companies "hire only the best". A good company for a junior developer will look for a person's "trajectory"- i.e. is a person willing and worth investing in to help them grow.
