Whenever I start learning a programming language, I feel overwhelmed by the number of popular frameworks, tools, and packages people recommend. Just when I understand the basics, another library appears that seems essential. Am I expected to memorize all of their functions, or is there a better way to learn and work with them? How do experienced developers keep up without burning out?

The useful skill is learning libraries quickly, not remembering every detail forever. Read the official documentation or tutorial, then make a small project with the library. It’s completely normal to keep the docs open while working—even experienced developers look up standard library functions and APIs all the time.
You definitely don’t memorize entire libraries. Learn what a library is designed to do and build a general sense of where to find the features you need. When you forget an exact function name, argument, or syntax, use autocomplete, documentation, or your own previous code. The parts you use regularly will become familiar naturally.
Prioritize programming fundamentals before chasing every popular framework. Focus on variables, control flow, data structures, algorithms, debugging, and how to break a problem into steps. Those skills transfer between languages and make learning any new library much easier.
Think of documentation like a reference manual, recipe book, or dictionary. Knowledge doesn’t have to live entirely in your head. Understand the concepts and the library’s general approach, practice by building things, and look up the less-common details whenever they come up.
Over time, try to build a mental map rather than memorizing details. You should know which tool can solve a particular kind of problem, then look up the exact method when you need it. You’ll eventually remember the small portion you use most often.
