Why is Spring Boot still used in large-scale systems despite newer backend frameworks?

I am learning backend development using Java and Spring Boot and have built REST APIs using it.

I noticed that newer technologies like Node.js and Go are becoming popular for backend development. However, many enterprise applications still use Spring Boot.

Can someone explain:

What advantages Spring Boot provides over newer frameworks?

In what scenarios is Spring Boot preferred in production systems?

Are there specific features (like dependency injection, ecosystem, etc.) that make it suitable for large-scale applications?

Looking for technical explanations or real-world examples.
