When was the last time you saw the Strategy pattern?
Here it is.
Imagine you need to process the state in some method.
There can be many ways to do it, and you cannot tell the right one up-front.
That's easy!
Ask for the Strategy.
Define an interface you want.
This interface transforms a string into a string.
Inject it into the class and use it in the place where you want to.
The ball is in the caller's yard.
They must provide concrete implementations and inject one each time they use your class.
That is great.
This is one of the best patterns in existence.
But the times have changed.
Why so much code when we can request a simple Func delegate?
Inject a lambda and remove all these verbose types.
Learn about object design from the long video.
Here, you saw how lambdas almost eradicated the Strategy pattern.
Think for yourself.
