Beautiful animations and presentation in addition to your awesome explanation obviously.

Thanks

Lydia , I have been following you for a long time, your github JS questions repo was amazing; it helped me get many jobs into good companies...kudos for coming up with this video...Thanks

Microtask queue is misnamed as there's no guarantee the tasks are actually micro. A better name would have been "priority task queue".

can not be simpler and more elegant way of showing the concepts, thanks for the lessons.

For the fist time I followed a channel in 5 mins only.

You got another subscriber here! Hope to see more content soon!

The best explanation ever!

Hey Lydia, How did you create this Visualized? In Advanced Thank You 😊

amazing,thanks you so much

Fantastic explanation

Excellent video, thanks for taking the time to put this together. Would you mind sharing what software you used for the animations? I'd love to create some courses internally at my company to teach newer employees and would really benefit from being able to make something in a similar style.

How did you make this animation? Can you tell me?

holy shit this is fucking greate

Amazing Video great explanation.

As soon as i saw that wiggle at 00:05 i knew it was Keynote! This video has lots of amazing parts that are just so recognizably Keynote, from the turning "refresh" arrows symbol to the items plopping onto the screen. I love how you did the moving boxes at 10:54 that disappeared while they moved, since that's one of the trickier part of Keynote animations imo. Did you synchronize a move action and an opacity action for the effect? Cause that's the only way i've been able to do it... Massive props to you for making this incredible overview, you rarely see people use Keynote to its full extent!

thank you it helped me a lot

This has saved my sanity on something I thought I could never understand.

This is brilliant! Such clarity💎😄Thank You!

Are you doing all these animations in keynote?

5:11 important moment here: setTimeout is not just magically gets push onto task queue, but on every event loop run there is check if we need to run some operations (check if set timeout delay is over, if callback was triggered etc.), therefore it's not guaranteed that set timeout callback will get executed exactly in n seconds, but it is guaranteed that it will execute *after* 200ms

Awesome and easy learn from you..

I might be wrong here but: Chaining thens example. First Promise is immediately resolved, all good, no problem. BUT, second Promise is NOT. Because result => result * 2 handler goes to Microtask queue and until all synchronous code is done, so all then() methods, handler is not executed and second Promise is not resolved. And so on...

How to create such executable video

This is the best lower level explanation of JavaScript I have seen. Thank you for the enlightenment as to how these things work!

This is excellent. The visualization helps so much! Also just drives home how much I prefer promises.

what is your use software ( sample code show )

Finally on KZbin!! Welcome Lydia, it is a privilege to have your content here for free 🙌

probaly one of the best explanation for Promise, thank you so much for this video🙏

Talk about Java and JVM core in this visualization

The best visualisation of the JS runtime I've ever seen! Respect Lydia!

Wow 🚀 This is the BEST explanation of promise concept I've ever seen. The visualization and your explanation work super well together 👍

Great Content, but you have to check your recording settings the volume is too low, I have maxed out my speakers and tried my headphones as well.

Ridiculously simple when you explain it. You just got new subscriber !

Magnificent Video...!!! I will share this video to all my Front End developers and my junior developers. It will give them a clear understanding of events and callbacks. Im convinced to subscribe to your channel.

You are sent by god to share such a knowledge.

This is amazing! Please keep the good work!

wow

This was so easy and good to understand keep up the good work!

4 months ago, I learned event loop from your dev.to post titled JavaScript Visualized: Event Loop - which is the best visualised minimalistic explanation I have come across, and then to refresh it, I watched this video you recently posted. Thank you Lydia Hallie.

Hallie thanks for sharing amazing video with backend concept and voice very good

You just got yourself a new subscriber! I actually watched a video about all these a few days ago and I kinda understood how it all works but this video is the icing on the cake, I now perfectly understand how it all works and it's all thanks to the beautiful visualizations you used and your straightforward explanation. This video is a goldmine ✅

That's a great video!. May I ask which software you used to create the slides?

New Knowledge Gold Mine ALERT!!!!!!!!!!! Fantastic work Lydia, thank you so much for this video. I'll be one of your subscriber for the entire of your youtube journey. Keep teaching using such mind blowing visuals which are sooo helpful in understanding the concepts. Thanks you again.

Thanks for another amazing video! This cleared up many questions I had in my mind regarding asynchronous code ✨

Wow. This video is beautiful and so are you! You explained it so well and there was even a quiz and awesome recap! New subber. Bless your heart. "Lydia oh lydia, i wish i didnt get rid of ya". Now that songs stuck in my head.

What tools do you use for this kind of animation?

You are the living example that THERE IS a difference between software engineer and developer. Your deep understanding of the tech, the way you can explain and visualize it, it’s astonishing. You‘re a true engineer. Kudos. And many thanks for the video.

Really Aswesome, Great Explanation. Thank You!

That's a really good way to explain something which can be complex trying to understand it without the visualization! Thanks alot for sharing this gold content!
