this is a great series, I was watching the egghead tutorials, but yours is much more down to earth and less assumptions that you know what your doing already. Thank you so much.

Maximilian is such a great teacher. It is hard to appreciate the work he puts into his tutorials, but if you have tried to learn this on your own or with a second-tier teacher you'll clearly see how great Maximilian is!

I know this video is 7 years old already, but thank you anyway! I'm glad to know the basics and core concepts when learning the current versions and how it evolved over time.

[ashleythomas]

Great stuff, thank you for taking the time to make a very good 'from the ground up' tutorial. Very clear explanations and a great pace as well.

You're really a great teacher for teaching us clear programming core concept. Thank you so so

[SergioArroyoSailing]

Thanks so much! bests simplest barebones explanation yet! Great idea to abstract away the other elements and just show Redux itself ! Keep up the great work! =)

[jonyoinas]

For the first time I really understood how the reducer works! ...state etc are no longer magic to me! Thank you so so much!

[maciejbak]

Nice described this "...state"

[jean-baptistelasselle]

thank you so much, again, very good explanations, and so, the spread operator does what we generally calll a deep copy

[kalia]

its really helpful and +1 for clarifying the spread operator and its overwriting behaviour.

[rvlglobe]

Golden nugget of knowldge, many thanks

[sylvain]

That is very clear. Thanks for your tuto

[generalco]

@4:25 I'm not quite clear on what happened here. How is result = 123 before the next addition and console.log is executed? How could it know unless the addition has already happened?

[tambolaking]

I was making this mistake in my application. Thanks

Hi Max!
Thank you for this video!
But it is not fully clear to me why do you create state object without any variable creation statement(like var, let, const)?
(line 44, 51) in the end of this video.
Because in this case state is not an existing one object which you override so it is a little bit confusing.
Thanks again
