Mithril.js

Mithril.js is a modern client-side JavaScript framework for building Single Page Applications. It's small (< 10kb gzip), fast and provides routing and XHR utilities out of the box. Mithril.js is used by companies like Vimeo and Nike, and open source platforms like Lichess. If you are an experienced developer and want to know how Mithril.js compares to other frameworks, see the framework comparison page. An easy way to try out Mithril.js is to include it from a CDN and follow this tutorial. It'll cover the majority of the API surface (including routing and XHR) but it'll only take 10 minutes. You can now update the label of the button by clicking the button. Since we used m.mount, you don't need to manually call m.render to apply the changes in the count variable to the HTML; Mithril.js does it for you.

Java

Oracle

The Java™ Programming Language is a general-purpose, concurrent, strongly typed, class-based object-oriented language. It is normally compiled to the bytecode instruction set and binary format defined in the Java Virtual Machine Specification. In the Java programming language, all source code is first written in plain text files ending with the .java extension. Those source files are then compiled into .class files by the javac compiler. A .class file does not contain code that is native to your processor; it instead contains bytecodes — the machine language of the Java Virtual Machine1 (Java VM). The java launcher tool then runs your application with an instance of the Java Virtual Machine.
