Really like your tutorials. Nice work. Also do more videos on more operators like when apply,

[@smartherd]

It is already there. Check Playlist for when and apply keywords

[@TroenderTass]

elvis operator is not really comparable to the ternary operator. The kotlin equivalent to ternary (condition ? a : b) is actually (if(condition) a else b). This has a return value just like ternary operator. The elvist just gives jo a default if a value is not there, the ternary operator lets you pick between to values based on an actuall condition.

Welcome

[@prashantsawarwadkar5127]

If suppose you remove ? after String while defining var and use valid name then all 4 operator works in the same way for a valid name like Steve.

[@smartherd]

Yes,? Just provides a safety layer in case your value becomes null in runtime.

[@vaibhavgupta973]

THANKS

[@gopaljee8490]

in 'safe call with let' : print statment is showing compile time error.. error:name is local variable that is captured by changing closure .. I thing we should use println(name!!.length) since we are sure that name can't be null

[@deepakgupta-zl2in]

The lambda expression present inside the let is executed . use it.length instead of name.length

[@JannisAdmek]

why doesn't Java have this by default? There should not be any NullPointerException in any compiled language!

[@smartherd]

Haha, that's by Kotlin is here to kick Java's ass

[@JannisAdmek]

@@smartherd Indeed haha nice video btw you nailed it!
