tutorial 4 please :)

[ShadowofCatron]

@jiminoc Alright, I promise I'll make it.

[Unbekannter0Nutzer]

at about 4:20 to 4:39, code śtarts like this:

def getOneFive () : (Int, Int) = (1, 5) /*and*/

println (getOneFive ()). Then you change the method to:

def getOneFive = (1, 5) /*and*/

println (getOneFive), saying 'we no long _need_ parenthesis here', while the red errormark clearly says, that these _must_ be removed; compiler: error: getOneFive of type (Int, Int) does not take parameters.

[ShadowofCatron]

@Unbekannter0Nutzer I meant that you can no longer have parenthesis there, there are not optional.

Thanks - very clear and very useful. Any sign of tutorial 4? :)

[ShadowofCatron]

@itsmahfaaaace Okay, I promise I am posting another one today... :)

[Placebo858]

this is just amazing how easy and fast you can write in Scala!

[imshenitsky]

how you get syntax coloring like this?

[jujufrenchy]

This is very useful, thank you. The syntax reminds me a lot that of VBA

[basmithtx]

The "Identifier: Type" syntax reminds me of Pascal. Ah, memories...

[De4sher]

looks nice

however i can't help remembering why someone would learn Scala: cuz they already know some 2 other languages, and want to see why this scala thing brags on being so damn scalable :)

could you skip to that part pls pls pls?

basic syntax is boring, give us some of that inheritance/ interfacing / multithreads :D

if i don't ask too much

[ieonqutav]

A really good video.

@ShadowofCatron thanks for these tutorials. Any chance to get tutorial 4 somewhere ?
