I bet nobody misses a single CS50 lecture at this university. I have learned so much from David and really appreciate that we live in a time where we can view this content without actually being there.

I have many watched many teachers over the years and I have to say that David malan is my favourite professor for cs. His passions every year never fails to motivate me.

[SaidakbarP]

Finally I can solve the last pset (pset 8). This is the start of great discoveries for us with the wonderful journey we had in CS50x! Thank you, professor Malan for the patience and dedication!

[LexChanKlaus]

Cool! professor is also the fan of Stranger things

Why this lecture doesn't exist in CS50 2018? It is so helpful.
Specially to understand what is Ajax, Json form, and JQuery.

[BekBrace]

I do use Visual Basic for Applications (VBA) to create macros and automation applications :)

[anestezialmanya]

Thank you all for making These all available.

[bluebird]

thanks cs50 for helping me take my first steps <3

[davlewis]

It would've been nice if he showed AJAX using pure JS before showing how it's done in jquery just so people aren't crippled by a library and can really understand what jquery is actually doing. Definitely would've been more verbose but a learning experience.

[siddharthjoshi]

Can someone provide the github link where i can access these codes.

[alexandernho]

Hey guys, what's your opinion on the coding sequences shown in MR ROBOT? Is is accurate / appropriate for what's going on in the respective scenes?

[robertoprince]

Hey javascript expert here.

use function fetch instead of a jquery.ajax.
use method document.querySelector an document.querySelectorAll instead of jquery.

to iterate over an array use methods array.forEach, array.map, array.filter and array.reduce.

in order to not suffer over the dynamic nature of 'this' pass the object, use arrow functions, use function.bind or avoid it completely using a functional paradigm pretty much suported by javascrit

1:31:28 - the instructor describes writing a program for the Mark Zuckerbot for his Congressional hearing.

Investing in NFLX would also have been a nice bet
