Hi Keerti, your design patterns series is really useful, thanks for the effors. I have one request, it will be great if you can solve some LLD interview questions and explain how design patterns can fit into the problem. This will really help us understand how design patterns can be used in real world problems
I love these design pattern videos. The code example helps conceptualize things better. I use this pattern all the time in my job, since it is part of MVC, where the data-model acts as the subject that is being 'observed'.
Hello Keerti, They was you explain the concepts and then code it up is super easy. I have seen a lot of design patter tutorials but yours is the best one I have come across till. Thank you so much.
When i started watching i thought you're going to talk about asynchronous js redux and all. But it was really good quick intro to observable pattern. In extra revised all oops concepts as well :) Thank you keerti
Didi I am requesting to your , please try to upload other design patterns. Your explanation is really appreciable. Just watch once and never forget..... Thanks a lot 👍
Guess what, I understand the pattern, but recently we had an old sms system without an API. I used Wireshark to decipher the packets, from an old app, compared it to a documented protocol and got it working with my own API client library. I did something similar for an old email server. I used the first library and extensive knowledge of email protocol and email messaging to create an email to sms gateway. cool.
Hi, You said you did used the observer design in 3 of your interviews. I would be interested to what was the context and how you used the design pattern. that way we can relate more to the real life examples. Appreciate you work.
Hi Keerti, I am currently working in a startup which has a tech stack of React Native, a hybrid platform to build mobile applications. I saw your other videos and see you have given a lot of interviews. Congratulations By the way! So in your opinion does current stack matter if I want to switch to a SDE role in big tech companies? Or DSA, HLD, LLD will be enough?
In class "Group", Can we have list of 'User' instead of 'ISubscriber' like "list users;" and also in other functions having "ISubscriber" ? Basically not having the "ISubscriber" class at all. What is the purpose of having this Interface?
Doubt : i have implemented it without using "ISubscriber" , instead i used "User" every where and it works fine. Is "ISubscriber" class really necessary ? if it is why ? P.S : Thanks for the playlist.I have watched all videos in this playlist its really great.
Why do we need ISubscriber interface ? since the notify method will be same for all users why create a redundant interface ? we can just create User class and make list it works right ? Please explain what am I missing.
You know what problems I have seen in your code....you have not used destructors in any of your Design pattern code...people may forget about destructor in interviews
I used factory design pattern in my interview recently. Your video on factory DSP was very helpful. Looking forward for other design pattern videos.
Thank you so much Smitha ❤️❤️

Watching youtube videos were never as informative and organised before. Appreciate your effort. and thank you so much😘
Your videos are very concise and to the point. Very good for strong basics.

You have simplified this pattern really well. Thanks a ton. Keep making more videos.
Top notch content di, eagerly looking forward for more videos in this Playlist...., this Playlist is going to be best on RUclips 💯💯

Thank you keerti
thank you ma'am for your simple explanation.
Very quick and to the point explanation of concepts 👍👍
Thank you so much! best explanation and thanks for making it in C++
Wow , I really liked it!!! I would like to have more examples on each pattern , please do suggest any resource for this !!
Nicely explained, plz keep uploading videos on design patterns
Please push design patterns videos quickly. It's really going to help a lot of beginners like me. Thanks for such a precise and quality content ❤️❤️
Great explanation mam, waiting for this type of content from a long time 👍👍👍👍👍
Thanks a lot for this insightful video!
amazing video
Thanks a lot for the clear explanation 😊
TOP CLASS ❤
Amazing content, and looks very helpful.
So a big Thank you.....😇
Great explanation!
Loved it . Nice and short explanation !!
Thank you so much ❤️😇
@@KeertiPurswani 😊❤️
Hello ma'am u r doing great..your explanations are so ... soo good..plz upload on some more patterns
Didi I am requesting to your , please try to upload other design patterns. Your explanation is really appreciable. Just watch once and never forget..... Thanks a lot 👍
great explained
Your always awesome.
Thank you so much for making things super easy.
Thank you so so much 🥺🥺🥺🥺❤️❤️❤️

I am subscribing ur channel by using ODP hope u will be notified if i understood the concept right 😝😝
much awaited, loved it. plz do the same for the rest of the patterns as well soon.
Coming up soon. Next one coming on sunday. Please do share with your friends ❤️😇
Why are pointers with memory allocations is done instead of direcly defining class instances?

easily explained ...

I work at flipkart on React native
In class "Group", Can we have list of 'User' instead of 'ISubscriber' like "list users;" and also in other functions having "ISubscriber" ?
Basically not having the "ISubscriber" class at all. What is the purpose of having this Interface?
Other type of class can be used as subscriber, which implements Isubscriber
Doubt :
i have implemented it without using "ISubscriber" , instead i used "User" every where and it works fine.
Is "ISubscriber" class really necessary ? if it is why ?
P.S : Thanks for the playlist.I have watched all videos in this playlist its really great.
There can be different types of subscribers with different kinds of notify implementation.
A well written code with explanation for code of Observer Design pattern us there in TechieContent medium article . Read that
Why do we need ISubscriber interface ? since the notify method will be same for all users why create a redundant interface ? we can just create User class and make list it works right ?
Please explain what am I missing.
I have the same doubt. Have you found the answer yet?
I'm just curious about "Why did you used list?" only. We can use any std::vector as well right.
could you please make a video on VISITOR Design pattern
In user ctor we shouldn't be using this pointer, rather we should initialise the memeber with initialisation list.
Is redux use this pattern,
Like whenever state change is re render all subscribeed components?
Can u explain it for python programming..
Why didn't we create the list with user class itself instead of creating another class Isubscriber. Please explain
You used a list and pointers to register users. Both are antiquated methods. It also is bad for performance. Use a vector instead.
is interface necessary here?
Hate the number of likes you get,like they're merely 8% of what you deserve according to the content you provide.
why not kafka?
Hi,
why did you create an interface ISubscriber and made your users implement that. What was the specific reason for doing so?
Hi Keerti, my friend (SS) is saying that kuch khaas nhi h is video me, Please upload a kuch khaas video on observer pattern for her😅
😂😂
Mam plz make a detail video DSA+python 🙏
can anyone please clear, why it is , list not list ?
@KeertiPurswani
@@shubhamtiwari7704 because you can have a different class as a subscriber
can someone provide the code snippet pls
Great video. Congratulation! However, I was wondering. Don't we have a memory leak each time we remove a subscriber?
Can you provide the Java code
You know what problems I have seen in your code....you have not used destructors in any of your Design pattern code...people may forget about destructor in interviews
Please give timestamps . It would be helpful
Marry me!
Great video, very simple explanation. Keep them coming
greatly explained
