What does the ESP button do in a Vauxhall Astra?

I recently bought a used Vauxhall Astra and noticed there is an ESP button on the dashboard. Can someone explain what this button does and when I should use it?

The ESP button stands for Electronic Stability Program. It is a safety feature that helps to stabilize your car during sudden turns or icy road conditions. You should turn it on during slippery or wet road conditions to improve traction and prevent skidding.

The ESP button is a lifesaver! It helps to prevent accidents by detecting when your car is about to lose control and it will automatically apply brakes to specific wheels to keep you on track. Make sure to keep it on at all times, especially in hazardous weather conditions.

I always turn off my ESP button because it restricts my driving abilities. It can be useful for some, but I personally prefer to have full control of my car.
