There are loads of people teaching you each individual "gang of 4 patterns" on youtube. you can look each one up individually, and find series after series going over them all. but i paid good, hard earned money for mosh's course. the reason why is right here in this video. if you want to really absorb this material, you need a teacher who will challenge you to open your mind and tackle the problem. everyone else just says "here's the answer". we don't need that. buy a book if you want that. if you want a teacher? a real lesson? a real class? start here. start with mosh. thank you mosh. timeless material... and yes, to anyone wondering, you can download and save each video. you will own a hard copy of the material, to sit next to your hard copy of the g.o.4. reference book. kudos.
I wish you had said at the beginning that this is the first video in a larger paid course. It took me a while to realize the video wouldn't actually be a 1-hour overview "course" of design patterns. I definitely felt misled by the title and thumbnail as someone searching for design pattern videos on RUclips. At the very end, you say you mentioned it earlier, but I didn't catch that anywhere at the beginning. 🤔
I feel scammed too... The video was very good, but I was expecting the full content about design Patterns to be in this video, not a PAID course. Did you paid the full course? I don't know if it's worth it for me to do it (just graduated from College with a Software Development AAS degree). I want to learn design patterns but usually tend to use free content online. Please anyone feel free to share your opinions on this comment!
@@danielguzmanramirez2281I’ve been studying from Mosh course’s about 4/5 yrs. And I can garantee you it’s worthy every single course I made from code with Mosh!
@@diManjenje88 Is understandable. I didn't know about him before. I watched the whole video and ended up paying for his Ultimate Design Patterns Course.

Am new in programming. I didn't know where to start. I watched many videos about python but I always got lost. But as soon as I watched your teaching, my God! am so happy I understand what you are saying. #you are a God sent Mosh. Thanks a million.
This is the best explanation of the OOPs principle, I felt like I've known nothing before. I've watched at least 20 videos on OOPs, none has explained it so well. Great content!
I'm only 9:52 in and I can already tell I'm going down the rabbit hole watching your videos. Great job! Love it! I already know this stuff to a certain degree, from using it all the time, but am trying to clean up my explanations in interviews and presentations and your video is clear and concise. Very nice job! Helps me think about the topics in really clear ways.
Just started this course but am very impressed so far. I just graduated with a diploma in computer programming but never really grokked design patterns. Thanks for all your work! I will be purchasing the full program.
Hi , Mosh, I learnt the React Native 2 years ago, your class is somehow clear and help me a lot . About this course, it gradually teaches me from fundamental to pattern design, its very friendly to absorb the knowledge, thanks a lot
Mosh! You are the hero! No, you are the super hero! Mosh for president! I just can't put all of my gratitude in this words. Thank you for all your support on my path!
I've been coding for 6 months and never used interfaces but learned (I thaught I had learnt them). I've done more than 20 projects to improve my coding skills and I think if I knew interfaces properly, I wouldn't have done a lot of coding repeating. I love them and I will use them ! Thank you
This was a fantastic lesson, Mosh. I'm a QA, but I'm always trying to understand the systems I'm working with better, and I was able to follow along - even with the more complex ideas - in a way I can't always do with other teachers. Thanks so much. Also, I hope your fans here in the comments call themselves The Mosh Pit. 🤘

But you explain things better than anyone.
Thank you so much for helping me get ready for the interview. Promise if I get the job and get cash I will be more than honored to support your awesome work.
I've been long waiting for this course done by you. Only $30!!! I already know most of the content, but even if I learn one or two concepts from this course, it values thousands of dollars to me!

I'm really really pleased by the way of your teaching. Thanks Mosh for helping us unconditionally. May God fulfill your every wish!
Hey !!! Mosh !!! just watched the Add without skipping, i hope it will add some dollars and keeps you motivated for making such awesome content for us !!!! Thanks !!!!
@@programmingwithmosh Hi! I couldn't find where it is the complete course. I've search on your platform but nothing. Can you send me please a link? Thanks a lot
I love how much effort you put into these videos. Changing Images and nice explanation makes this the best video for the topic. Came here because my lecturer was just reading the slides, and the slides was confusing
in the encapsulation part, the withdraw method should also check if the amount you want to withdraw is available in the balance otherwise the balance will go negative :D

Encapsulation is a notion of grouping together the state and behaviuor inside of a class i.e. coupling variables and methods which work together.
What you (start to) explain on 22minutes is access control(aka "data hiding" or whatever), not encapsulation.
Encapsulation and access control are two separate things.

I am using your course(Data structures & algorithms and Design patterns) for my interview preparation. But I am missing system design course. I have seen few other tutorials. But you explain things better than anyone.
Thank you for the course, just needed at the right time. I have interview tomorrow, and if I pass, all credits to you

Hi Mosh, I'm Kartick from India. I want to learn Oracle from A to Z. Mosh can you please upload full tutorial on Oracle Enterprise 19C from Beginners to Advanced level? There are no quality tutorial for OracleI on RUclips. Please help me Mosh. I need to learn it as soon as possible. I found no one on RUclips, who can describe and teach so beautifully. I'm really really pleased by the way of your teaching. Thanks Mosh for helping us unconditionally. May God fulfill your every wish!
