Whenever I study a new technology or concept, I end up following every unfamiliar term I encounter. For example, I might start learning concept X, find concept Y in its explanation, and then feel I need to understand Y completely—including how it works, why it was created, and where it is used—before I can return to X. I repeat this for nearly every new topic, which makes learning frustrating and easy to lose track of. How do experienced software engineers structure their learning, decide which details to postpone, and retain enough information to build on it later?

Start by understanding why the technology exists and what problem it was designed to solve. Once you know where the problem starts and what a successful solution needs to achieve, the surrounding concepts become much easier to place. You don't need to understand every detail immediately; fill in the gaps as they become relevant.
Begin with an overview of why the technology is useful and how it fits into a larger system. Then learn the basics through documentation, videos, and small experiments. After that, build a practical project or add it to an existing one. The project will show you which details actually matter. Once you have a working understanding, you can either rebuild it with better performance or move on to the next topic.
I try to view software as separate components connected by a larger architecture. First I learn each component's high-level purpose and how it fits into the system. The low-level details usually make more sense when I have to use them to solve a real problem. Working with familiar patterns and keeping each component focused on one responsibility also helps me understand what matters and write code that other people can follow.
Learn the fundamentals first: common use cases, the basic architecture, and how the technology is normally applied. When you want to go deeper, study its performance considerations and best practices, but also look at situations where it failed or was the wrong choice. Understanding limitations is especially useful when comparing similar tools.
I hadn't thought much about studying limitations. Most explanations focus on when to use a tool, so learning when not to use it seems like a useful way to understand it better.
That makes sense. How do you figure out the cleanest or most standard way to implement something, such as authentication, instead of just making a solution that happens to work?
