What topics or areas within your professional sphere do you find most interesting?

In the field of Node.js, I am particularly interested in the following topics:

• Asynchronous programming and working with promises, async/await for efficient data stream management.
• Creating RESTful APIs and microservices using Express.js and other frameworks.
• Working with streams for processing large volumes of data.
• Performance optimization and scalability of applications.
• Integration with databases (e.g., MongoDB, PostgreSQL) and caching.

These areas allow creating reliable and fast server applications, which is very interesting from a practical application perspective.
