What is the purpose of the Audi A4's electronic stability control feature?

I've heard that the Audi A4 comes equipped with electronic stability control, but I'm not sure what it does or why it's important. Can someone explain its purpose and how it works?

Electronic stability control, also known as ESC, is a safety feature that helps prevent the car from skidding or spinning out of control while driving. It uses sensors to detect when the car is losing traction and applies braking or throttle control to specific wheels to keep the car stable and on the desired course.

ESC is an essential feature for maintaining control and reducing the risk of accidents, especially in adverse weather conditions or emergency maneuvers. It can also help inexperienced drivers maintain control of the car.
