What is the main role of the Spring Core module in the Spring ecosystem?

Spring Core is the fundamental module of the Spring framework, providing essential capabilities for building applications. Its main role is managing the lifecycle and configuration of objects (beans) through the Inversion of Control (IoC) container and Dependency Injection.

Spring Core is responsible for:

• Creating and managing beans within the container
• Resolving dependencies between objects
• Supporting configuration via XML, annotations, or Java code

This allows developers to create flexible, easily testable, and extendable applications, separating object creation logic from their usage.
