Angular Interview Practice

Which best describes the component structure in Angular?

1. All components are global

2. Encapsulated into reusable components

3. Fixed component structure

4. Components are only for UI display

The correct answer is: Encapsulated into reusable components

In Angular, the component structure is best described as encapsulated into reusable components. This means that each component is designed to be an independent, self-contained unit of functionality that can be reused throughout the application. Components are the building blocks of Angular applications, allowing developers to break down complex UIs into smaller, maintainable pieces. Each component has its own template, styles, and logic, which promotes a clear separation of concerns and facilitates better organization of the codebase. This encapsulation also enhances reusability; once a component is created, it can be utilized in different parts of the application without needing to rewrite the functionality. Additionally, Angular provides mechanisms such as inputs and outputs to allow communication between components, fostering modularity and flexibility in the overall application architecture. The other choices do not accurately represent the fundamental principles of Angular's component structure. Components being global would reduce modularity and lead to challenges with maintainability. A fixed component structure contradicts the dynamic and flexible nature of Angular's architecture, which encourages developers to create components that can be easily adapted and reused. Lastly, while components do often handle UI display, they are not limited to this role; they also encapsulate the logic and data manipulation associated with their specific concerns.
