This video was a boost to my self confidence. I was working with the Wikipedia API for the first time and thought I must be doing something wrong because it was so many steps. Then I found this video and thought, "Hey, it's not me, it's Wikipedia."

Using all those "shortcuts" but writing counter = counter + 1

1:28 : *<h1>...</h2>* - most big brain moment in the history of web development

9 times... (counter = 0, counter = counter + 1, counter < 10). I like you're doing little mistakes, feels more natural\not rehearsed.

Hey Dan, would you ever consider doing separate videos where you go into depth explaining topics that you briefly touch on in the coding challenges? For instance, jsonp, or something similar. I think it would be very beneficial to have a separate video for those that want to go in and learn the details about what you are talking about.

Moral of the story:

Wikipedia programmers must watch tom Scott’s programming videos...

Dear god man, you have no idea how much that probably just helped me with my a level computer science coursework!
Thankyou!

hey Daniel, as always great Video! could you do an episode on the YouTube API? I think that would be fun - and also maybe go deeper into how to secure the API-Key? I really struggle a lot with this security stuff.

This is how I use Wikipedia. I search for something about IT stuff and 2 hours later, I end on a page about "8-Oxo-2'-deoxyguanosine"

Thank you so much! I like your way of telling the code and allowing to have a mess in your thoughts, it helps to focus and see that Programmers don't have to be perfectly focused people!!!

Man I wish i had coding skills like this. I LOVE designing interfaces, but this just seems so much cooler with the right knowledge and skill

RicoGalassi

I actually like and enjoy to see your coding challenges, the way that you explaind, the way that a programmer thinks it's a cool things. Nice job in every single video. Keep it good, and stay good as always, seeing this far from a computer to start coding, lol

for those who cant get result from loadJSON() function with 'jsonp' parameter,
change your p5.js cdn to version 0.6.0 or eariler.
In ver0.6.1 p5 will throw an error if you try to load a json file with jsonp format. It should work then :D

thank you for doing these, reminding me when im stressed that coding is fun! and im proud to say I finally know enough vanilla js that I could write this, and follow what the p5 lib is doing for you, slick stuff, useful indeed.
