I seen so many youTuber to learn this pattern in 35 or 30 mint long videos.the funny thing they did not teach me in 35 mint which you just did in 7 mints. superb

God bless you. I was trying to read my textbook for all of these strategies and was ready to throw my laptop at the wall. This is simple to understand even for beginners. Thank you!!

I have seen almost all the design pattern videos on this channel. They are to the point, explain concepts with relevant examples. Kudos!

[gerardofranco]

Clear, simple explanation, great video! I would also add that this pattern not only applies the Single Responsibility and Open-Closed principles, but also the Dependency Inversion. By using this pattern you avoid that your high level modules (in this case, PaymentService) have dependencies with your low level modules (CreditCard implementation, Paypal implementation, Bank transfer implementation, etc)

This channel is an amazing complement for the book design patterns, really great to see the patterns explained in video after reading about the details in the book, thank you

Fenomenal, as the other videos in the series.
The fact that you gave context, explained differences and showed up an example in only 7:26 mins says a lot of your experience.
Keep it up! You bring so much value into the community 🚀

The interviewer was good. From low to high. ❤

[mfiveer]

Great explanation! I've seen a few vids on the strategy pattern but this one definetly stands out :)

[adamee]

Its so unfortunate that I found your channel only now. Top notch explanation!

[tucanalfavorito]

Thanks for this video I didn't understand it at my university but now I understood all.
Thanks 😊 .

[anuragtripathi]

Really amazing content with real life examples. Good work (y) . Subscribed! :)

[vengateshm]

Very clear and pragmatic comparison with state pattern.
May be I will spend a week to go through all your tutorials and take notes and then will attend interviews.

Would like to know your profile.

the first example also violate dependency inversion since the 2 class must depend on abstraction instead of each others .. reducing coupling between the 2 classes

[christopherreif]

I really like how you break this down.

[fusionmantra]

thanks alot for this video i learnt this example from ur video and same question is asked in interview n they are impressed for it 🎉 thanks alot for the video

[moisesdepaulodias]

amazing videos! great explanation, thank you very much.

[rayunn]

Thanks for those very clear explainations 🙏

[andersontiban]

Wow great video thanks, what are books or online resources that bridge the gap from “beginner” knowledge such creating a class, for loops , etc .. To best practices and design patterns ?

[mayankpratapsingh]

Thanks for such an amazing content. Could you please let me know how did you design the intro of this video ? Which app did you use ? Where can I also get such amazing videos for an intro ? Thanks in advance!

3:47 - in the main function, you have to set the payment strategy anyways based on the user's choice of payment method. So you will have to have some logic (conditions) around choosing the strategy like you had in the initial code (if (creditCardPayment) { ... } else if (paypalPayment) { ... } ...). How would you elegantly deal with this?
