Scala: Beyond the basics with Christopher Batey

What can you do in Scala that you can’t do in Java? Why are streams and lambdas not enough for functional programming? What are the practical uses of more advanced language features?

We’ll cover specific language features with their uses cases:

Function composition as an alternative to layered architectures
Functional approaches to implement dependency injection
Writing reusable code with higher kinded types
Avoiding mutability with expressions
Abstracting with type classes
As well as posing some higher level questions about language features:

Why do we embrace runtime reflection frameworks but fear compile time implicit parameters?
Ease of initial understanding vs long term productivity of a language
Simple vs familiar language features and patterns
The goal of this talk is for you to learn some specifics about language features not yet in Java as well as to get you excited about programing languages in general

Amazing talk, puts everything in order. Thank you!

[stoaeterna]

Fantastic talk! I am a junior in scala and this was illuminating, thank you.

[cyphen]

Brilliant. This is exactly what I was missing.

[pharmajoe]

Great explanation, best I’ve heard! Cheers 👍🏻

Wow all of those forms of futures... Really glad JS has basically switched everything to native promises for all new things

[leftover]

Excellent distillation, Christopher! Up there with Torreborre and Spiewak. Could you become the next Odersky or Milewski or Martin (presenter wise)?

[Minimingus]

Brilliant, finally made higher kinded types click for me

15:07 ha has been using c for Customer and p for Person then in the trait CustomerRepo he uses p for Customer :p that is why we should always name variables properly

[sateforp]

14.43 method ending with a c :) looks like a typo. would prob rename it to customer and type a return customer even though it is not needed make the code clear to understand?

[sateforp]

registerCustomer also violates command / query separation ? and it is interesting how the method is called register customer then calls save customer inside :)

[DaveGouda]

This guy is Richard Hendricks in real life

[farooqmss]

Countless times he avoided "spring framework "
Annotation based framework, framework using reflections, rest controller and service, dependency injection, DI based framework
😂😂😂

I will be very happy when next fashion communication visual idea will be more efficient by just use 100% of screen to target the interest of subject (the code), instead of use less than 20% for targeted subject and 80% for decoration and kind of human chatterbox. This world actually is more like appearances more then reality and efficiency.

Beyond the basics.... Proceeds to talk 48 minutes about the most basic sh*it ever.
