> 1. Lambda functions can be defined with {}. Directly "stolen" form Scala. > 2.foo(bar, somefunc) is the same as foo(bar) somefunc. In other words, if the last parameter is a function, it can be provided AFTER closing parenthesis. Just a irregular syntax quirk that tries to get around the fact that Kotlin does not support multiple parameter lists, like the language where most Kotlin features come form, Scala. > 3. Interfaces that require only one method can be implemented on-side with a lambda function (i.e. {} syntax for no-param function). That doesn't have anything to do with Kotlin. That's Javas SAM (Single Abstract Method) feature. > I'm surprised author didn't mention it. The author seems not to know any Scala. Otherwise the lists would show mostly only Scala features… ;-) |
