Bridge Pattern:
The Bridge design pattern is a structural design pattern that splits a large class or a set of closely related classes into two separate hierarchies: abstraction and implementation, which can be developed independently of each other.

In other words, the bridge pattern decouples the abstraction from its implementation and provides a bridge between the abstraction and the concrete implementation.

Imagine you're building software for a universal remote control that can interact with different devices like a TV, Stereo, DVD player, etc. You could create a separate remote control class for each device, but if you add new functions to the remote control (like mute or volume up or down), you would have to modify each of these classes. Also, if a new device is added, you would have to create a new remote control class for that device.

Implementation in Go:


The Bridge pattern allows you to separate the abstraction (remote control) from its implementation (devices), so they can vary independently.

In this example, the function PressButton() can be seen as a bridge because it connects the abstract part (a generic remote control that presses a button) with the implementation part (the specific device that gets turned on). If you want to add a new device, you just need to implement the Device interface. And if you want to add a new type of remote control, you just need to add a new type of RemoteControl abstraction. They vary independently, which is the purpose of the Bridge pattern.
