People always tell me my videos are too long and slow 😉 so I decided make a short and quick series called "100 Seconds of Code". Please like and comment if you want to see more!

[ResoCoder]

Even if you know about this stuff...


You're still gonna watch it because of the animations.

[abdoufma]

You better have 50 more of these already prepared for us Jeff, because this is the type of quality content that people want!
As always, keep up the good work :)

[RyanJohnson]

I'd totally watch a playlist of a whole bunch of 100 second explanations :)

[ionk]

It's unbelievable how you compress so much information in 100 seconds, really wow!

[ninjachickn]

I love this type of content, its easy to consume and does a fantastic job of explaining the concept! Keep up the good work my guy!

[AntiApplelife]

This is the start of something special

The first ever video from 100 seconds series

[FilledStacks]

You're very inspiring Jeff. As you know you're the reason I started making tutorials and where I get my fast paced style from. You always deliver more value and better content. This is a great video, thanks for the effort.


... the idea. I definitely might steal it haha ☺️

I just love how simple it is to use array map. Map an array in just one line, no boilerplate, no bullshit.

[BromanThings]

I use your videos all the time for myself & to teach students when they are struggling, or I need to show them a new way to think about an issue. Love your content.

What music is this!?

[RIFOU-FF]

the beginning of a legendary series...

[JohnnyPhoenix]

The _Promise.all_ trick blew my mind. Can't believe I've never done it this way, it's **measures** cleaner. Nice!

[islamibrahim]

So this was this beginning of the 100 seconds of code series. I always learn something new in these videos, even going back. One thing I just learned is mapping args to fetch.

[BrendansReasons]

Wow the voice is different back then. I watched back then as well but jumping back is like wow

[azatecas]

Omg im literally learning this in bootcamp and as i look it up you released it. You always got my back homie lol

[laurelineparis]

Loved it, was not expecting having a better understanding for imperative or declarative way of writing code ( did read about but was never sure of the texts meaning )
Those recap are priceless, good job!

[blessingschishimbakalambai]

I really think it's very helpful, but do more flutter dart videos too you got some of us hooked on it and you upload less content on it.

[judamix]

great video 🚀🚀
can you make a 100 seconds video of switchmap() and tell us the difference between it and map() please.
thank you a lot for sharing

Map implementation is usually out of order execution in which do not block executing thread and data is generally returned with notification and call backs. Anyone who has done threaded programming with chunked data would know.

Well, modern programming languages these days are abstracting these work patterns and getting out of programmer's sights. Also it can be implemented on MP instructions and be exposed directly, there are literally lot of ways to implement this functionality.
