I've been doing web development for around 3 years now. I probably don't know 50% of what's on this roadmap. Unless you're working as a sole developer on a project, you can get away with not knowing a whole lot of stuff. I couldn't set up webpack for a project if my life depended on it. To be fair, I spend a lot more time doing back end development. But even for the back end development pathway, I don't know anything about web sockets, GraphQL, message brokers, ElasticSearch et al, NoSQL, or caching with Memcached/Redis. It's not that I couldn't learn how to use all of the above, but rather that it's just something I don't have to use at my job. Most employers don't/shouldn't require you to know these things in order to get a job, they are skills you can learn on the job. The ability to learn is the most important skill an employee can have. The rest is just decoration.
