CS50W - Lecture 6 - User Interfaces

[@qwertyui2827]

The best Javascript course I have ever seen. Lots of things packed there, and everything is very clear, easy to re-use right away.

[@joshuaroehm5644]

I’ve watched one video and learned more than I did in 5 weeks in my web programming course

[@ri8176]

True, I never understood JavaScript in online courses. Harvard explained it pretty well!.

[@Duge6124]

The experience you got from those 5 weeks was most certainly useful for you to understand and appreciate this video as well

[@freeeagle6074]

@@Duge6124 absolutely right.

[@zinglobi7717]

from your failure you learned many things

[@sayori3939]

@@zinglobi7717 no, It's from proper resources like this one you learn

Huge respect to the tutor for the way he covered necessary stuff for teaching react with a simple game. Loved the flow of lecture!!

[@puyakhalili]

amazing! Out of the countless number of react, tutorials that I’ve watched over the years, thus one was the only one that was able to convey the philosophy behind the library in very simple terms.

[@FamilyFoxesLoveChannel]

He explains everything he writes and I appreciate it because it helps a lot to beginners like me, thx bro

[@lamkhoi1304]

This is why Harvard is your dream university!

[@gowinidea]

Thanks Harvard and the instructor for creating and sharing this class to the world!

[@space_0027]

He’s a really good lecturer. Very clear and engaging.

[@Zealotux]

The course I wish I had when I started out, good luck to everyone learning the web, take it easy :)

[@chromashift]

This; as I begin to understand more, I realize I've merely learned how to navigate the space with it's discourse conventions; as such, while it's exciting to try everything I still have to be selective with learning projects (only have 24hrs in a day)....

[@mobileLegendFunMoments]

Any time I get any problem related to these topic I just watch this video again and again. As he used react and explain this is the best way to use react, and can save some computing 🖥 power of my poor i3 laptop becz that react compiler need lot of ram as windows does. Thanka for explaining these all topics. This is like 4 or 5 th time I m watching this video.and in this just one video I learned more than I learned in last 2 months. I can just say thanks 😊 to Him for explaining thinks in well organized way.

[@jalilmalik1409]

Another excellent Lecutre. Appreciate if the code Brian used is downloadable for practicing.

Write the code as the the lecture goes on like i did and after the lecture try to make changes using your own brain.

Hello world, I love cs50

[@rayroman6209]

I can't catch up now the pacing differs from the previous Lectures Luckily the pacing returned during the React Discussion

[@vovaka440]

Thank you for the information! :)

[@makhmud_jumanazarov]

Hello, thanks for information

[@ademineshat]

Great course and very well explained. I would like to ask: is it a better practice to write or include JavaScript at the end of the body? I know you used onDom content loaded but still?

[@rishabhgupta8876]

I think the best practice is to include the script tag at end the of the body. I don't know why he doesn't do it. Maybe to show an extra feature of js but who knows.

[@christopherstephens161]

@ 29:37 he finally trips over his words in all the lecture Ive watched

[@makumarrr385]

Can we get complete deep lecture on React ?

[@BudetSvobodnoy]

because the video is edited. If it wasn't - you would hear him trip over his words much more frequently)

[@AyeshaAtif-j1v]

ahahahahha

It Is Fantastic lecture

7:12 I don't understand the procedural js and not oop php

[@ella-cyndyb-johnson4105]

27:22 Nothing is showing up on my screen. Can someone please help? The JsonResponse doesn't seem to be working and when I input /posts or /posts?start=1&end=10, I get the following message: Using the URLconf defined in scroll.urls, Django tried these URL patterns, in this order: admin/ [name='index'] posts [name='posts'] The current path, posts/, didn’t match any of these.

[@bndissanayaka]

I am learning from scratch and wondered why he uses DOMContentLoaded all the time; I searched and found this answer. Hope it will help a noob like me. The DOMContentLoaded event fires when the DOM content is loaded, without waiting for images and stylesheets to finish loading. Only handle DOMContentLoaded event if you place the JavaScript code in the head, which references elements in the body section.

[@franka4312]

guys i need some help i've already implemented load post page, but when i reach the end of the page insted of loading just the next 20 post, it loads 200!!! or 60 or 80 i searched for a solution but i couldn't find anything.

[@buihung3704]

It might be that the web check the event multiple times. Try to make a boolean flag to force it capture only once.
