What is the purpose of the electronic stability program in a Audi A2?

I am wondering about the function and benefits of the electronic stability program in an Audi A2. Can someone please explain to me what it does and how it helps with the car's performance and safety?

The electronic stability program, also known as ESP, is a safety feature that uses sensors to constantly monitor the car's steering and movement. It can detect if the car is skidding or losing control and automatically apply the brakes to specific wheels or reduce engine power to help maintain stability.
