How you guys read documentation to learn new stuff ?

As a fresher who got placed in an MNC during college, I usually learn new concepts by taking crash courses or watching YouTube tutorials. However, when I asked some experienced seniors for advice, they emphasized the importance of learning through official documentation. I gave it a try, but it just doesn’t seem to work for me, and I’m struggling to implement what I learn.

How do you guys approach learning and implementing new technologies effectively? Any tips or strategies that work for you ?
