I learnt Python, SQL and Java from your Tutorials and I'm here to learn JavaScript from you again. You not only teach how to write code and the syntax but also how to think like a proffessional software engineer. You are the best Mosh

Unlike most online code tutorials, this (series) is well-organized, clearly and simply explained and it moves along at a good clip without being overwhelming! Kudos!

I cannot believe this video is free... This is the the best javascript tutorial I have ever seen.

Glad to hear that, Pett. It's my first approach to Javascript OOP (did it before with PHP) and this video makes it super clear!

Love your videos, Mosh ❤I did struggle with tutorials. What really worked for me were Books and Mosh`s Videos. Edit: For those asking, I started learning with a basic book named Javascript In Less Than 50 Pages, which is very beginner friendly. Then I improved my skills with another one named Head First Javascript Programming. With those books I finally learned and wanted to share what worked for me.

Probably the most aesthetically pleasing on-line JS course I have ever had. :)

great explanation Mosh, you are the simple, concise and best.

I mean, seriously, this is the next level of free learning content on KZread. So many videos out there on coding. But for me, so far, this is the best laid out course I've found. Kudos to Mosh! I'm going to deep dive on your channel so hard :)

Mosh you give the best, cleanest, explanation on everything. Great teacher!

Just an update for new viewers. The `class` syntax is now widely available in JS after ES6. It is somewhat a syntactic sugar to defining a constructor function like shown in the video.

Mosh I come from the VHDL Verilog background to understand OOP. You given here an excellent knowledge and awesome lecturing. Love your videos. Now I am more loving to learn software programs after watching your videos. It is just not the knowledge gain, but you really inspiring and made to jump into a full fledged learner on JS and C++. Simply incredible work you doing here and helping the Software community. Thank you

Your awareness of your viewers' different programming contexts make this video very unique, in the JS space. Every mention of how the equivalent is done in C#/Java is much appreciated..!

This is by far the best tutorial I have ever seen in my life. It is so well organised, well-mannered and you've made JavaScript seem like a piece of cake. Truly magnificent! Keep it up.

thanks mosh, you are one of my best teacher. best of luck.

a very good explanation, keep teaching like this! thanks

Really great! The points that I couldn't have got yet in anywhere else have got here... Thanks MOSH

It's a very good tutorial... it's just a pity that JS is terrible for OO

Great tutorial. I had a little bit of trouble with the exercise but I eventually figured it out. One thing I did differently was in my "duration" getter, I added an 'if' clause to check if the stopwatch was running. If it was, I set the duration to the current lapsed time at that moment, then returned 'duration'. That way you would always be able to see the duration, even if you haven't stopped the stopwatch yet.

49:25 : Best closure explanation for me so far. Thank you Mosh!

Hi Mosh, first of all, I would thank you for your amazing videos. I have +3 years exp as a dev. What I like about your courses is your way of explanation. The way you teach is likely the way of the academic teaches but with a magic touch! Most instructors on KZread ignore the identifications like what closures, abstraction, ...etc mean? and they are so important to know especially for the interviews!

Thanks Mosh for this great wonderful tutorial. Keep going.

We do have classes in JavaScript. The classes were introduced after ES5 in the JS.

Hi Mosh! Great tutorial, it really helped me a lot to understand the basics. I will definitely continue with the rest of your videos. But I found the example with increase() function a bit confusing. I am not skilled enough, so maybe I am mistaken, but at 34:15 - 34:42 the same result (number = 10, not 11 as you stated in video) will return (if we add "return" of course) because of operator i++, which returns a value before increment.

I'm sure you've found this out by now, but just to be clear for others, Mosh and you are both right in this regard. When you pass a variable as an input parameter to a function, its copy is being passed, not the original variable, hence any changes made inside the function will remain inside and never make out of that function.... unless you use a return statement to update the variable outside the function (as you said). To add onto this, this problem is solved by using pointers in C++, thru which you can pass the "reference" of that variable to a function and then no copy is created.

Wow, i am watching this now, and so far this is the best explanation of OOP i have ever encountered. Thank you!

Mosh was just AMAZING at explaining OOP, I have learned so much in 1h! BIG THANKSSS

I would like to explain oop in #arrowFunctions as methods a little bit for dear developers in here: If you use factory function, then you can NOT use #this keyword in it because it refers to the window object. But, If you use constructor function, then you can use #this keyword because it refers to our own object.

As an italian, I almost drop out of my chair seeing a salad on top of that spaghetti dish at 2:40 😅 Other then that, EVERY SINGLE WORDS on this video still actual in 2023!! Hands up to you 🎉

Best vid found in js, for intermediates and experinced js devs so far. Definitely gonna buy the course 😃

43:45 - It called Encapsulation, not Abstraction. Abstraction is something else in OOP

Thank you! I finally start to feel like I understand objects!

A MUST watch video before interviews!! Thanks Mosh

so far the best video on OOPs java-script. I really appreciate your hard-work and efforts.

Finally a tutorial on how to write OOP in JS ;-; Thanks a lot, it makes sense and I don't know why I couldn't get to this by myself. It's very simple :)) The most interesting thing for me was using the "in" operator to check whether an key is in an object or not though, I've always used "Object.keys(obj).indexOf("key") > -1" 😅

@@shreedharsharma4745 honestly mate, I can't learn with courses and stuff. I learned programming by trying out different stuff. It started with keybinders with Autohotkey (simple scripting language) and I just advanced as I tried out new stuff. Get yourself some random web page from the internet, maybe something from dribble and try to create your own copy of that website locally. Think abt stuff you would do differently. Check out some portfolios of devs and look at their projects. The best way to learn programming in my opinion is by trying. This video helped me because I already knew how object oriented programming works with other languages and I never really thought abt it in JavaScript. This video gave me a better understanding of how functions and objects etc work in JavaScript and helped me organizing my codebase in JavaScript projects :)

Mosh I come from an OOP background and I was really confused with objects in Javascript. Fortunately, this tutorial cleared up a lot of things. However, I am wondering if these are worth knowing since ES6 defines proper objects via classes and not by functions as shown here. Will this be covered in your course? thanks

@@sanal4492 so there is a class notation (syntactically) but in background, it works as a constructor function.

Thanks for detailed video Mosh, this has really helped me to upskill my JS knowledge on the area of OOP.

Heads up for those coming to this tutorial in 2023, setting variables like shown in example: let duration, startTime, endTime = 0; will actually lead duration to be undefined and when you try to add seconds to it in stop function, it will produce NaN. Correct way is: let duration = 0, startTime = 0, endTime = 0;

You taught so much in the introduction, I thought the video ended at 8:48. lol

Amazed on how simple you make the things, mate.

I am a .Net developer and interested on learning JS. always had some problem with understanding the JS. I found this course really helpful as it also compares the C# and JS . thanks a lot

I agree. I think a simpler example would help. I'm still learning, and that part tripped me up.

This is a great video! I've recommended it to many of my classmates. Just a small suggestion, maybe in the example, instead of 'circle, radius, location...', you can use something easier to understand like 'user's info', 'apples', 'shopping list' etc. to make the learning process even more smoother. I know that circle is easy to understand already XD but every time I see radius and stuff like computeOptimumLocation, it takes me 1 second to react >

50:00 explanation about closure. Scope variables are recreated everytime the functuon is called and scope limited to inside of braces. Closure allows function to access parent functions members as well.

You lost me when you said on 10:44 :: "This is no for begginers, it's for intermediate level developers, so you need at least three months of experience programming on javascript" So I'll practice and see you in 3 months sir, or less, who knows :D great video btw
