Return and Throw with the Elvis Operator | Kotlin Tips

[@churraskindequeijo8418]

The best thumbnail ever

[@Kotlin]

True

[@sebastianaigner9125]

Probably my favorite part of creating these videos! 🤣

[@henninghoefer]

I think Seb has achieved peak thumbnail!
(also, I really liked the opening gag "Today Elvis returns. Or maybe he throws.")

[@sebastianaigner9125]

I'm always trying to make each thumbnail more interesting than the last! 🤣

[@cicerohellmann]

Man, I really appreciate this videos, it feels really chilll, you learn something new and and it's always enjoyable to hear someone that is enjoying it.
Thank you

[@sebastianaigner9125]

I'm glad you're enjoying the vibe and are learning something new with my videos, Projeto!

[@DanielThirion]

Seb, your thumbnails are so funny. Keep on going.

[@sebastianaigner9125]

Thanks Dan! They're great fun to make!

To avoid nulls in Strings I prefer to put a ?:"" at the end.
I call it Elvis duck face.

[@cockyboby]

Wow what a lesson! Whats next? Dot operator?

[@abhimanyu.n14]

I like elvis like this as well.
If a function has a nullable parameter, we can use
variable_name ?: return (or throw as required)
This is without assigning it to a new variable.

[@raphaeltarita5187]

this Nothing return type of certain keywords is pretty wild, it actually allows for some, well, not really useful, but pretty funny expressions. As an example, if a function takes a parameter of type T, then you can actually call it by supplying 'return' as the parameter: function(return). This doesn't actually "do" anything at runtime, it's just funny how this is actually a valid expression to the compiler

[@park2348190]

'nothing' type! impressive

[@ryanhaining4004]

I'm not sure what c or c++ operator you could be referring to as similar to ?: unless you're thinking of some language extension?

[@JoseGarcia-bn6kq]

Could you explain variance and covariance in one of these videos? 😜

[@rafaeldelacosta1811]

that thumbnail tho :))

[@xetra1155]

Would you rather use elvis or the helper functions `check()` or `require()` to assure that the following code is reasonable?

[@Mohit-il9gx]

It's been 4-5 years of kotlin js + react native still no one is using it (or handful ) company's are using it ..?? Did kotlin js failed....??? What are guys doing you have to be aggressive in marketing your product make kotlin js popular upload videos of cloning some popular website. introduce this language course in university make this language popular or every is gonna move towards flutter or javascript framework for web

[@ibrahimal-zaidi6436]

That is good.
My question is how to study data structure in kotlin?
It would be helpful if you can recommend me some resources.

[@ananthababu8272]

👏👏👏

[@TimSchraepen]

Yay! Result type next? 😬

[@sebastianaigner9125]

Honestly, great idea Tim! Seems worth covering in a future tip!

[@nguyencodervn]

Thank

[@lukalukovic5082]

Can anyone explain to me the double colon operator :: in kotlin?

[@sid.h]

You can also
foo?.let {
// do something that is conditional on foo existing but that doesn't require the explicit handling of the null case
}

[@ДмитрийБречко-м9с]

Thanks i like this videos

[@GakisStylianos]

I came here just to praise the thumbnail 😅

[@uwumarie]

Wow what a Thumbnail

[@cipriandroid]

Title should contain ?: instead of :?

[@MsCpktnwt]

Hello guys I am using opencv with Kotlin in android. And I want to find Contours but in c++ we have vec4i but in Kotlin what I have to use .

[@Zeeshan-Syed]

Or we can run a run {} block.

[@karthickpotter2211]

I read as "evil is back"

[@Kotlin]

😄

[@alco8864]
