Agreed, sorry.

Yes. You can mix Kotlin and Java in the same-project. Kotlin can call all Java-code and Java can call all Kotlin-code.

One of Kotlin's design goals was 100% compatibility with java. Whenever I work on a java-codebase and see a class that could be expressed much simpler in Kotlin I press "Cmd+Option+Shift+K". Intellij IDEA automatically conver

Kotlin is 100% java-compatible, you can mix source-files side-by-side in one project. You can easily call kotlin from java and java from kotlin. That means you have all the libraries, performance and profiling tools that java has.

While no-one would dispute the need of proper design, there are workflows like refactoring React/HTML-subtrees, where time is wasted having to fix imports whenever you cut something out and put it into a new file. Or having to manually

Reducing cognitive load by removing the need to write imports by hand means you have QA-issues? I don't follow.

I use eslint-plugin-auto-import and eslint-plugin-jsx-import (the latter I have hacked together for myself, it's undocumented and brittle) It get's triggered on each save in TextMate, which I use.

Off topic, but whenever I see an animation of someone writing an import-statement in Javascript by hand I cringe a little. This stuff costs so much time, use an IDE or some auto-import plugin for eslint.

I used extensions with multiple receivers for adding context inside data-structures. Example: I have a layout-algorithm for a grid that takes sections: interface Section { val title: String fun something() } The

If you got time, play around with extensions with multiple receivers, you can do pretty neat stuff with them. See my comment here: https://news.ycombinator.com/item?id=14365317

* A feature I like about kotlin are the receivers, with which you can write type-safe builders: https://kotlinlang.org/docs/reference/type-safe-builders.htm... * Multiple receivers are possible enabling extension

Off topic: The more I think about organizations the more I they seem to be the key players preventing change to me. (Which is not necessarily a bad thing) Business says: We had this great idea, now let's freeze everything in time and l

I did all the benchmarks on Android ART. It's not the JVM, but blocking GC is an inherent design problem of finalizers that can't be fixed on any VM.

Assuming you don't do heavy work in the UI-loop: I find react-native's bridge memory-management on Android rather questionable: [0] They make heavy use of structures in native memory for argument-passing between JavaScript and Jav

Also many common problems like targeting the correct Jdk, customize start parameters and classpath, shipping agents, selecting native libraries etc. are nowadays better solved by using capsule for packaging. It gets you a single jar without

I've started writing a fuzzer for the JVM once. It looks at the bytecode and adds instrumentation to check whether a label has been hit = a code-path has been traversed after calling methods. It uses genetic algorithms to spawn agents

You are wrong. Most interfaces in non-functional languages are stateful. Take the JDBC-interface: It's certainly not possible to call setTransactionIsolation(), executeQuery(), commit(), rollback() etc. in any order. Or list: add, remo

I try to use interfaces that have single methods only. The problem with multiple methods is that you can abstract away the function call, but you can't ensure the caller is the methods in correct order (if that matters, but it often do

Unfortunately not, since those apps are all business internal. On Android/react-native, the Kotlin parts runs on the JVM directly. I haven't released a KotlinJS-application to the wild yet, but I don't suppose the size is a p

I write most my code in Kotlin nowadays, which can compile to JavaScript, or drive react-native on Android. It has delegated properties which are wonderful for redux-style architectures.

In my opinion mutable state is most often better than immutable state. In JavaScript, that is, I have a different opinion on the JVM. The important point is that the state is _serializable_, meaning it doesn't contain side-effects. Tha
