答案:TypeScript Modular App System refers to a design where an application is divided into separate, interchangeable modules, each with a specific functionality. This approach allows for better maintainability, scalability, and reusability. Key concepts include:
1. **Modularity**: Breaking down the app into smaller, manageable pieces.
2. **Encapsulation**: Keeping the internal state and functionality of a module hidden from others.
3. **Reusability**: Creating modules that can be used across different parts of the application or in different projects.
4. **Interoperability**: Ensuring modules can interact with each other through well-defined interfaces.
5. **Scalability**: Allowing the application to grow by adding or updating modules without major overhauls.
6. **Maintenance**: Easier to update and fix issues in specific modules without affecting the entire system.
In TypeScript, this is often achieved using namespaces, modules (with `export` and `import`), and potentially module loaders or bundlers like Webpack.
