JetBrains’ Kotlin JVM language appeals to the Java faithful

Kotlin, a high-performance, statically typed “pragmatic language” that leverages the environment of Java Virtual Machine, has reached its official 1.0 release milestone. Created by IDE makers JetBrains, Kotlin — like many other non-Java languages that run on the JVM — is meant to run where Java runs and make use of the existing culture of Java libraries and tooling. Java, in turn, can use items built in Kotlin.

Isomorphic JavaScript: The Future of Web Apps – Airbnb Engineering

This idea isn’t new — Nodejitsu wrote a great description of isomorphic JavaScript architecture in 2011 — but it’s been slow to adopt. There have been a few isomorphic frameworks to spring up already. Mojito was the first open-source isomorphic framework to get any press. It’s an advanced, full-stack Node.js-based framework, but its dependence on YUI and Yahoo!-specific quirks haven’t led to much popularity in the JavaScript community since they open sourced it in April 2012.

A JavaScript library for building user interfaces | React

Just the UI Lots of people use React as the V in MVC. Since React makes no assumptions about the rest of your technology stack, it’s easy to try it out on a small feature in an existing project. Virtual DOM React abstracts away the DOM from you, giving a simpler programming model and better performance. React can also render on the server using Node, and it can power native apps using React Native. Data flow React implements one-way reactive data flow which reduces boilerplate and is easier to reason about than traditional data binding.

Flux | Application Architecture for Building User Interfaces

Flux is the application architecture that Facebook uses for building client-side web applications. It complements React’s composable view components by utilizing a unidirectional data flow. It’s more of a pattern rather than a formal framework, and you can start using Flux immediately without a lot of new code.
