What do you use to learn new technologies?

To learn new technologies, I use a comprehensive approach:

• I read official documentation and specifications to understand the basic concepts.
• I take online courses and watch video tutorials for practical understanding.
• I study source code and project examples on GitHub.
• I write small projects or scripts to reinforce my knowledge through practice.
• I discuss questions and share experiences in professional communities and forums.

For example, when learning new features of Go, I first read the release notes, then try out the new functions in small programs to understand their behavior and limitations.
