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.

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

This single Java class benchmark, shows impressively that the penalty for using StringBuilder instead of regular String concatenation can be around 5x ! Many static code analyzers like PMD / SonarQube deceptively claim the opposite. This assumption might be a vestige from the pre Java 5 era. Indeed some developers even concatenate compile time constants ( static final ) using StringBuilder. Although be warned , when it comes to using effectively non-final variables inside the concatenation, StringBuilder will drastically outperform the regular String concatenation by several orders of magnitude. Effectively non-final variables are references that are not fixed. On the other hand effectively final values do not necessarily need be prefixed with the " final " keyword but they could be , which differentiates them from effectively non-final variables, that cannot be prefixed with the " final " keyword without causing a compilation error. To state it clear ...

The builder pattern can be used to provide a kind of virtual dynamically extendable constructor to build e.g. a model class for RESTful requests where not all fields are required but many fields are optional. public class ClientRequestModel {     private String url;     private String headers;     private String parameters;     private String body;     public ClientRequestModel(Builder builder) {         url = builder.url;     }     public String getUrl() {         return url;     }     public String getHeaders() {         return headers;     }     public String getParameters() {         return parameters;     }     public String getBody() {         return body;     }     @Override     public String toS...
