You're looking for the appropriate language?  Kotlin  might be the language you're looking for! Here you can find some sample projects that show how it can actually be done: Sample iOS app, written in Kotlin, using Maven or Gradle for building   —  this is how it looks Browser app that shows how Kotlin can access HTML's DOM  — this is  how it looks Browser app written in Kotlin that uses HTML5' Canvas  — this is  how it looks Another Browser app that shows how Kotlin can be used to build HTML5 apps   — this is  how it looks …all projects should work out-of-the-box.

This is the  source for a simple Kotlin (JavaScript) HTML5 Canvas app  that lets one type a random series of letters. And this is  how it looks like .

I just published a simple  Kotlin/JavaScript "getting started app"  that  shows the Unicode characters for a specific decimal range. And  this is how it looks like .

 This  GitHub repository  provides you with detailed instructions and an out-of-the-box working sample project to get started with Kotlin and its JavaScript transpilation  capability.

If you are using Spring annotations like  Value(" ${repositoryServiceUri} ") in your Kotlin code, you might get compile-time errors like these Error:Kotlin: [Internal Error] org.jetbrains.jet.utils.KotlinFrontEndException: Exception while analyzing expression at (16,14) in /Users/alex/my/project/loxal/rest-kit/src/main/kotlin/net/loxal/soa/restkit/client/RepositoryClient.kt: repositoryServiceUri Error:Kotlin: Compiler terminated with exit code: 2 because the ${blub}  notation is also used by Kotlin for expression and literal resolution. So just add a backslash like Value(" \${repositoryServiceUri} ") and everything is going to be alright. 

Check out the  code  and check out the actually  deployed and working showcase app  :)

Creating DTOs  in Java, you often end up with very verbose code, similar to the following Address data class: public class Address { private String contactName; private String companyName; private String street; private String streetNumber; private String streetAppendix; private String zipCode; private String city; private String country; private String state; private String contactPhone;  public String getContactName() { return contactName; } public void setContactName(final String contactName) { this.contactName = contactName; }          // 90 lines of getter / setter code has been omitted here!   } Studies have shown  that there is a correlation between code size and erroneous code . Hence reducing code size results in concise code which improves readability and understanding of the underlying solution idioms. The following Kotlin data class  with merely 11 lines of code re...
