Explain the concept of micro frontends and how they address the challenges of developing large-scale web applications.

Micro frontends decompose a monolithic frontend into smaller, independent, and manageable pieces that can be developed, tested, and deployed separately. This approach allows teams to work on different parts of the application concurrently, using different technologies if needed, which enhances development speed and flexibility. Micro frontends address challenges like scalability, maintainability, and team collaboration in large-scale applications.
