Can you explain what is meant by the term 'js-core framework' in the context of JavaScript development?

The term "js-core framework" usually refers to a minimalist or basic framework in JavaScript that provides essential tools and structures for application development, without unnecessary abstractions and additional features. Such a framework focuses on the core — state management, routing, basic utilities, allowing developers to build applications from scratch, adding only the necessary components.

For example, in the Node.js ecosystem, it could be a lightweight framework that offers basic capabilities for creating server-side applications, without complex layers and dependencies. This allows for better control over architecture and performance optimization.

Thus, "js-core framework" is a foundation for building applications in JavaScript, providing a minimal set of functions necessary to start development.
