It really is an exciting time to be a Web developer. There are extremely fun technologies out there that make our jobs enjoyable. However, as I mentioned above, don’t expect to learn these technologies overnight. It takes years to get to a reasonably proficient level, and the process of learning (as you would expect) never ends.
A great way to accelerate your skills, however, is to learn directly from practicing developers. And, while there is no substitute for in-person instruction, a growing number of online courses and tutorials are available that search engines are doing a great job revealing at the top of their results. So, begin by searching for tutorials and articles in the languages, libraries and frameworks of interest.
