If you get lost inside nested scopes, remember that 'this.' always refers to the innermost one, which is useful for making sure something comes from the current scope instead of being inherited from an outer one.

Use ‘it’ only in the simplest scenarios, when its type is clear from the context. Otherwise, introduce an explicit lambda parameter or use member references. It’s especially important for call chains where the lambda parameter type changes from one call to the next

The Kotlin/JS Gradle plugin ships with webpack-dev-server. Together with Gradle continuous builds (using the "-t" run configuration argument in IntelliJ IDEA or by invoking ./gradlew -t run), you can have your page reload automatically whenever you change your code.

So here's idiomatic range iteration in
#Java and in#Kotlin. One may say that the Java way is just a little more verbose while Kotlin provides syntactic sugar to express the same thing. But even integer ranges as first-class citizens is more than just sugar.pic.twitter.com/vFLeYjqQjt
