Design Patterns: Strategy

This is the second of an eight part series where Robert is joined by Phil Japikse to discuss design patterns. A design pattern is a best practice you can use in your code to solve a common problem. In this episode, Phil demonstrates the Strategy pattern. This pattern enables an algorithm's behavior to be selected at runtime.

such a great series. rewatching all of them before software architecture exam later this week

I love the videos but I don't know why there is not a playlist for design patterns as I want a sequence to learn all the design patterns. Overall it helps a lot.

I appreciate you guys so much for you work! It's good quality, yet simple! Good job!

I thought the description of "changing behavior at runtime" was confusing because it just sounds like just regular conditional logic, like an if/else or switch. But the superhero example clarified it and especially the "do your thing" phrase. I would recommend just highlighting that the different strategies are being defined in a different place than they are being executed, whereas in simple conditional logic those are together.

I think that is what 11:45 is about. The demo code doesn't really capture it, but they do talk about that fact several times. I agree it would be cool to have flashing letters to really drive the point home haha.

This is great. Thanks for sharing

How many accounts do you have? Or you trading from a single one? tell us pls

[@kesavanarayana6257]

It very helpful if you can make video on dispatcher pattern

[@burnsnewman]

I think a stateless example would be better.

I have seen lot of playlists on KZbin for design patterns. This is by far the least useful for developers. it is good if you are real amateur and and want the intro paragraph as a dialogue. Chapter 1 is never coming. Too much philosophical talk.
