How do you update and expand your knowledge of various programming languages?

To update and expand knowledge about various programming languages, I use several approaches:

• Reading official documentation and specifications — helps understand current features and best practices.
• Online courses and video tutorials — structured way to learn new concepts.
• Practice through projects and exercises — the best way to consolidate knowledge and understand nuances.
• Reading articles, blogs, and discussions on specialized resources (e.g., Medium, Stack Overflow, Hacker News) — to get acquainted with new trends and solutions.
• Participating in communities and meetups — exchanging experience with colleagues and experts.
• Studying the source code of popular libraries and frameworks — helps understand idiomatic ways of solving problems.

This comprehensive approach allows me to stay updated with changes and quickly adapt to new languages and technologies.
