Learn 2D Vectors with JavaScript

[@___d3p1]

Great explanation! I wish in my studies I had been given a teaching as graphic as this! I hope I can have time these nights and I'll try to share an object-oriented version of your excellent implementation :)

[@Radu]

Thank you. Yes, explanations are typically not so 'graphic'... I think coding adds to the understanding because you have a way to interact with the math... But if you look at this just to learn the math, there are better resources out there.

[@___d3p1]

Hello @@Radu! How are you? I know it's been a while, but I was able to find an opportunity to implement a forked version of this implementation. I am very grateful for the content and insights you bring to us!

[@Radu]

@@___d3p1 I didn't expect anyone to do it so quickly :-)) Wow, it's really great. I like that you created that graphic vector class which can display them at any location. Is there a real need for bootstrap?

[@___d3p1]

Thank you very much @@Radu!

[@2difficult2do]

Awesome explanation! It's great because instead of "dry" terms and formulas, you show it through step-by-step coding and illustrate how it can be applied in practice. Thank you!

[@Radu]

Glad you liked it :-)

[@CTFlink]

That's a sub and a like right there. I'm 39 and really appreciate a chance to learn the fundamentals in a more calm way.

[@Radu]

Thank you :-) glad you liked the content!

[@pesterenan]

This is so cool! One of the first things I did while learning programming in Java was to make a "Vector" class. I know it may already exist, but it's great to learn how to make a "library" or how to construct functions that can be reused! I still use it on my personal projects! :D Nice one Radu!

[@Radu]

Yeah, I have same memories about making a "Vector" class. Also similar memories about "Complex numbers" class :-D I often use those things today, as well, in this video I didn't want to make it a software engineering lesson... leaving it up to you guys (maybe I learn something new :-D)

[@scieszy]

I wish you continue with this series it's much fun

[@Radu]

I might, let's see :-)

[@scieszy]

@@Radu I'll trust you when the matter is about math Dr. Radu

[@mihirramaswamy1313]

I can see you going very far in the future. Don't stop

[@Radu]

I might have to slow it down soon :-) been publishing quite much recently.

[@NoelLang]

thank you for your tutorials :)

[@Radu]

Thanks!

[@chessketeer]

This is fun! Thank you very much🙂

[@Radu]

You're welcome :-)

[@vladyslav-py-js-cs]

Great explanation ! Thank you😁

[@Radu]

Glad it was helpful! :-)

[@alishata8]

Great as always👏

[@Radu]

Thanks!

[@javifontalva7752]

6:39 you can also use save() and then restore()

[@Radu]

Yes. I've seen them being used a lot... save at the beginning of a function, restore at the end. I think it's a good practice.

I’ve been looking for good videos about programming and math , thank you so much ! I’m a self taught developer and it’s great to be able to learn this stuff that you typically learn in a university. If you ever have a math + programming course on Udemy I’d be more than happy to Purchase it Keep up the good work Would also love to see some geometry

[@Radu]

Thanks for letting me know about the Udemy thing. I'm not interested in making money... at the moment, at least. But someday I'll consider it. Also... typically, at university you learn these things separately (math lecture about the math, coding lecture about coding, they are rarely combined like this). But I have seen others combine things in this way, and if you're both interested in coding and math it's ideal, I think... Coding also gives you a way to interact with the math.

[@RailGunViolin]

@@Radu it doesn’t have to be amount money you can publish a course for free In Udemy . It’s just nice to have it as structured content . You can probably even take your current videos and publish them as course. I think you’re a great teacher and it might be a nice way to get more people to consume your content. It’s really fun to combine math with programming, again thank you !

[@Radu]

@@RailGunViolin I actually made the self-driving car course with Udemy in mind, but just as I was wrapping it up they set a limit for how long free courses can be. And mine was over that limit, so I didn't publish it there as a result.

[@RailGunViolin]

@@Radu oh I didn't know that Udemy has a time limit for their free courses, I think that paid courses are up to 40 hours but i`m not sure.

[@georgecrisan9499]

Thanks

[@Radu]

Wow, thanks!

[@sergeys5270]

Great explanation! Thank you!

[@Radu]

Glad you enjoyed it!

[@javifontalva7752]

Are you going to make more vids on Math? I hope so. I really kike learning Math through coding since I don't seem to get it by the traditional method.

[@Radu]

Happy to hear you're able to learn in this way. I just posted a video like that but you saw it already :-)

i love your code 😘😘😘😘😘

My code loves you back :-D

@@Radu Thanks Sir😍😍

[@alwysrite]

could you please increase the sound on your videos? thankyou.

[@Radu]

I will try. Thanks for the tip... It's something I do struggle with (different equipment in different rooms...)

[@anthonystevens2156]

I subscribed to your website but the email sent to me had a broken link. I was able to fix it but please checkout the format of your outbound Email Confirmation Email. The HTML for the web link to confirm is invalid.

[@Radu]

Wow, really? Thanks for pointing it out... I'll try to make time and fix it one of these days...

[@realsubhajitpatra]

Hi sir, how are you 😌?

[@Radu]

Good. Thanks. And you? :-)

[@vincentcleaver1925]

I got incredibly confused...

[@Radu]

Oh :-\ maybe the explanation can be improved. Which part was most confusing?

[@green6232]

Like your generic!@@

Thanks :-)
