One of the most important things you can do to improve your WordPress skills is to learn all about WordPress hooks. If you’ve spent any time looking through code, trying to write a plugin, or referencing the Codex then you likely know:
Hooks are provided by WordPress to allow your plugin to ‘hook into’ the rest of WordPress; that is, to call functions in your plugin at specific times, and thereby set your plugin in motion.
Yes, I think it’s important to understand the event-driven design pattern. And it’s one thing to have a comprehensive list of everything that’s available regardless of if it’s an action or a filter but it’s another thing to actually see it action.
Given that we all have different learning styles, sometimes I think having a reference is only one way to go about learning how to leverage the system. Another way would be to use a plugin like Hookr.
