What advantage does a "Web Block" provide in application development?

A Web Block in OutSystems serves as a reusable UI component, which provides a significant advantage in streamlining the application development process. By encapsulating UI elements along with their logic and structure, developers can create components that can be easily reused across different screens or modules within an application. This not only saves time and effort but also ensures consistency in user interface design and behavior throughout the application.

The ability to make changes centrally to a Web Block means that any updates or enhancements made to it automatically propagate to all instances where it is used. This reduces redundancy and simplifies maintenance, as developers do not need to modify multiple screens individually when a change is necessary. Consequently, the use of Web Blocks can lead to more efficient workflows and help maintain a cleaner codebase, making application development more manageable and cohesive.

The other options do not accurately represent the primary advantage of Web Blocks, as they focus on single-use components, API integrations, or data processing libraries rather than on the fundamental principle of reusability and streamlined development processes that Web Blocks provide.
