Googling every hurdle as it comes & over relying on StackOverflow is neither effective nor satisfying. Some of the projects out there have amazing documentation (e.g. VueJS, Kafka). It's best to read the overview & skim high level stuff to understand the core components/principles/terminologies. It makes it so much easier & enjoyable to use those tools.
Give everything a good read before really working. You don't need to remember everything, but you need to know what's there so you don't wind up reinventing wheels, endlessly googling with the wrong search terms, or doing things people who use the tool correctly find inscrutable. It's so important.
I will note that this is much easier to do well when you're a more experienced engineer than it is when you're just starting out, but getting used to doing it and going back over docs when you do have more experience is the best way to get used to it.
In short, good official documentation is scarce and time to read is even more so.
