Hey Daniel! Amazing video, but can you share when variables are useful? I had a bad experience usig vals with a collection of pojos and after switching my pojo to vars I gained a little bit of performance. But I'm still not sure if it was right. Thanks!

Hi Daniel,
Please help us understand what sequence to follow the videos on youtube?

Great Video Daniel, I was thinking why Scala people just remove the while loop from language itself

Is there any use case for which they support it?

If not use variable, how I can update fields that their values are regularly changed?
