What is the main advantage of prototyping during application development?

The main advantage of prototyping during application development is that it provides fast development tools for user feedback. Prototyping allows developers to create a preliminary version of a software application that demonstrates its features and functionality. This early version can be presented to users, who can then provide valuable input on their requirements, interfaces, and overall satisfaction with the design.

By involving users early in the development process, prototyping helps to identify issues and adjustments that need to be made before final production begins. This iterative approach means that the end product is more likely to meet user expectations and requirements, reducing the risk of major changes needed after the full development is complete.

In contrast, the other options do not accurately capture the primary benefit of prototyping. While final testing is important, it typically occurs after the prototype phase. Prototyping does not eliminate the need for further iterations; rather, it is designed to encourage them by continually refining the application based on user feedback. Furthermore, while prototyping may involve using multiple programming languages, seamless integration of those languages is not a primary advantage of the prototyping process itself.
