What is the advantage of the Kia Soul's dual clutch transmission?

I've heard about the dual clutch transmission in the Kia Soul, but I'm not sure what it does. Can you explain?

The dual clutch transmission in the Kia Soul offers faster and smoother gear shifts, giving you a more responsive driving experience.

It also helps with fuel efficiency, as it can switch between gears with minimal power loss.

I've noticed that it also performs well in stop-and-go traffic, as the dual clutch transmission is able to switch gears quickly and smoothly.
