Seriously can't believe someone so knowledgable and organized provides all of this information for free in an extremely well-set-up format.... awesome work man

[technicalsuranii]

This guy is legendary scala- Captain America with rich experience and focused content delivery. Cheers up..

[AliJay]

This is what I have been waiting for ages, brilliant work 👍🏽

[Filaxsan]

Man, you are a legend. Not only the info were super useful and understandable, but you kept going for 3h+ straight! True hero! :D
Impressive job, subscribed for sure!

[yegor.karimov]

I'm watching it for 45 minutes and just wish to say that it is a truly beautiful course. I enjoy Scala's concept itself and the explanation.

[MohammadHusain]

Awesome! Not only the content but your energy to keep going for hours was super impressive!! Needless to say I learned a lot.

[prabhakaranrajendran]

This is very amazing video. For scala, we need these kind of simple videos & tutorials more to involve more developers to scala group.

Thanks again lot.

[wafleezr]

This is amazing. Currently learning Scala with the coursera course, I'm going to have this as an extra resource! Really looking forward learning Scala

[shreem]

Not many instructors have a sense of humor who can grab the attention all through. Thank you for sharing 😁😇

[rastislavsvoboda]

very cool, thanks for sharing
just some mistakes due to you were tired:
@2:16:19 your chess board is not square ;-) chess rows is 1 to 8

@2:21:33 your fibonacci is factorial ;-) should be fibonacci(n-1)+fibonacci(n-2)

[igf]

even before I've watched the content (I will!), yet I vote with 1 thumb UP for the title itself ;) :) Looking forward to look inside your webcast. Thanks!!

[bigben]

I cannot be more grateful! Thanks I am really learning from scratch after programming all my life in Python

[estebanmarin]

Thank you so much for this content, it gives a clear picture of the features of the languages in a straightforward way. I mean, I should read all the Scala - Odersky manual, but this video is the cheat sheet. It will be my go-to reference when there is too much syntactic sugar laying around

[MrTelarin]

Wow, this is actually amazing video. I watched a lot of "tutorial" videos in IT sphere and this have to be one of the best. On current project I've faced Scala for first time and they're using Play and Akka frameworks, maybe you can advice some greate resource to "crashcourse" those frameworks? Or maybe there is som great book about Scala?

[mariogamer]

Best video of Scala explanation, mas helps a lot my learning keep doing the great work. It's all we need and it's difficult to find such video quality thanks

[miguelluna]

Great crash course, I was pretty rusty on scala and this was really helpful.

[soporboyschannel]

Great explanation in one, thank you, man!!! Happy New Year!

[struan_mclean]

Thanks a lot for this tutorial helped out a lot!

[akkiaaa]

Excellent ! That’s what I wanted ! Thanks so much for these scala videos
