Great visualisation for the event loop with the micro and macro tasks.

[danielgilleland]

I love your work, and I'll be sharing it with my fellow teachers and my students. Bravo!

[JoaquinHernandezMartinez-ucsk]

thanks for the video, honestly it's in depth, clearly explained and a joy to use for review. Please do more

[mameenomar]

What is being used for the visualizations?

[aredrih]

I might be wrong but I'm pretty sure the method `return` and `throw` are part of the Generator's spec and not Iterator's. Also Generator's `next` takes an argument while Iterator's doesn't.

Most structure expecting an "Iterator" usually uses the Generator method so if you had to implement one manually, sticking to the Generator specs makes sense.
There is one use case were I find a difference through: if you share an Iterator between multiple loops (ad hoc queue/multi consumers), any loop breaking will causes a call to Generator's `return` method which will put the generator in a done state and end the other loop (no more value).
If you have an iterator, there is no `return` method and the other loop will exhaust the iterator.

Thank you for this Lydia. That was great.

I subscribed with front end masters content was good but not having clear roadmap most of JavaScript is there which tutor I should start with ??

[SebasCC]

Does anyone know what tools was used for the visualization?

[akash-kumar]

Just few words "Keep it coming, please".

[Kenbomp]

Suggest to ask if super should be used

[MaciejJureczko-ze]

That video is great, and You are great.

[Leonidn]

I’ve been working as a full stack dev for over 2 years now and I’ve never had to dive this deep. Am I doing something wrong ? I’m genuinely curious how this is useful in the real world if you’re not building apps from scratch

[FeLiNe]

I see. The "return" keyword inside the generator functions is just to confuse people.

[FragZero]

nice video... just one little fix class Dog { construct(name) this.name = name ...

[firiasu]

Nice voice and quiz! I didn't make a single mistake, I'm too experienced...

[Sindoku]

She basically has a quiz that are very similar to the questions I ask candidates when hiring other web developers during the theory interview round. I’m an architect at a fortune 30 company in finance, one of the top two banks in the world for reference. I’ll be checking this out, God willing. Seems like a lot of fun!

[VladPutin-fm]

omg I'm so stupid. Javascript is so evil, I love it :v

[Sindoku]

That last function looked a little iffy.

[omega.developer]

It's not free. Sorry it's disappointing 😢
