Learn to code a to-do list app in JavaScript – Part 1

We’re building a to-do list application from a simple design sketch, using HTML, CSS and JavaScript. This video was meant to introduce you to DOM manipulation and Event handlers in JavaScript, all that while building something cool and useful!

Hope you learned something new, and if you enjoyed the video and you’d give it a thumbs up I would really appreciate it!

Also if you have any suggestions, feedback or requests I would love to hear it. Blast that comment section or spam me on social media, I love interacting with you guys.

MightyArtss says:

One thing that I’ve noticed is that there’s some sort of a bug when removing items. If you have two items, if you delete the one that is on top (at position childNodes[0]), it works fine. But if you click delete on the second item, it will again delete the first item on the list. Looking for a solution to that atm

J Canan says:

Hey Max, how’s the app doing, did you go further in developing it ?
I invite you to have a look at an article we wrote about some features a to-list should have, we’d love your feebacks: https://blog.zenkit.com/7-mistakes-to-avoid-when-tackling-your-to-do-list-acbddbedabf7

can we create this app for android phones using javascript?

Morten Dalsgaard says:

Thanks! This is awsome! Way too quick for me, I have to constantly pause and backtrack to check if I got everything, and I often don’t. But even though it is a difficult and long proces (I use aproximately 6 or 7 times the actual time you use, because I get lost and have to start from an earlier point) it is great. I can’t do 0.5times speed because it makes me very sleepy (: and quite frankly it is humiliating for me to notice that you type quicker than me at half speed (:

I love the feeling of working on something that I can actually use for something (: It is a great practise while i am reading and doing courses on htmlcssjs.

I really-really-really like that you are showing the actual proces and workflow with errorfindings, mockup checking, googlesearchs and everything. Also love the occasional “yes!” or “Nice!” when it works and and and the motivational comments, great, seriously, this is the most fun I have had with coding sofar! (been a hobbycoder for a couple of years now)

I want to have the todolist on my portfolio and I hope to actually use it as a todolist for all the things I need/want to make on my portfolio. I haven’t seen the second part yet. I am hoping it will show how to make the list items permanent when refreshing the page, if not I will just hardcode that and have this as a plaything demo.

Other things I hope will come in the next part is how to make an entry with enter. I also have a little hope about drag and drop functionality. But no matter what I am looking very forward to see what it will contain.

Sweet Sorrow says:

This video looks more about CSS than JS. 45mins for CSS and just 15mins for JS. Dislike

Arman Handa says:

Vela Farquharson says:

This was incredibly helpful. Thank you!!!!

Leon Hoffmann says:

Cool stuff Max! :)

Hassan M. says:

Hi Max. I was trying to test your code in Android Studio. html and css apparently work fine, but there seems to be an issue with the javascript code. If I type in a todo and either press “enter” or click on the button, unfortunately nothing happens. In the browser is was working fine. Do you have an idea, what the problem could be?

Hamza Azeem says:

Best! ..
Please Do more video like these ..

JAro Keraj says:

super tutorial:) congrats:)!!

Jarno Grooten says:

I have no idea whatsoever why javascript isn’t working except for an alert window, I looked it up but everybody suggests a timing issue which it is not since the script is at the bottom within the body tags.The code is correct and the same as in the video, frustrating as hell..

Paiz Hamdani says:

Max you might want to try using Sass. Its save so much time with the “DRY”.

casy azmon says:

thanks dude..

Hassan M. says:

Thanks for this tutorial, Max! I finished part 1 and 2, but I can’t figure out, why the width of my header is wider than my todos, although the settings in style.css are identical. Any idea?

chiel de Leeuw says:

Great video. I managed to get this working but do find a responsive problem. On mobile the to do list does not seem to scale that well.
