Script# 0 votes

C# Developer Goodness, JavaScript Deployment Bliss!

Script# is a development tool that generates JavaScript by compiling C# source code. It is especially interesting for scripting-in-the-large scenarios that is commonplace in the current generation of HTML5 and script-based Web applications.

Script# lets you leverage the productivity of C# (intellisense, build-time error checking, natural language syntax), and the power Visual Studio IDE and standard .NET tools (such as msbuild, refactoring, unit testing, static analysis, code visualization, fxcop). Script# brings all this to you without abstracting the runtime environment - you're still authoring script, just with a different set of tools.

You can even use Script# to work against other existing frameworks and APIs such as jQuery, jQuery plugins and Knockout, and can be extended to work against other existing script.

Unfancy JavaScript

CoffeeScript is a little language that compiles into JavaScript. Underneath all of those embarrassing braces and semicolons, JavaScript has always had a gorgeous object model at its heart. CoffeeScript is an attempt to expose the good parts of JavaScript in a simple way.

The golden rule of CoffeeScript is: “It's just JavaScript”. The code compiles one-to-one into the equivalent JS, and there is no interpretation at runtime. You can use any existing JavaScript library seamlessly (and vice-versa). The compiled output is readable and pretty-printed, passes through JavaScript Lint without warnings, will work in every JavaScript implementation, and tends to run as fast or faster than the equivalent handwritten JavaScript.

LiveScript 1 vote

a language which compiles down to JavaScript.

LiveScript is a language which compiles down to JavaScript. It is a fork of Coco which is in turn derived from CoffeeScript. Like those two it has a relatively straightforward mapping to JavaScript. LiveScript is Coco but much more compatible with CoffeeScript, more functional, and more feature rich. LiveScript aims for increased expressiveness and code beauty.

While adding features to assist in functional style programming, LiveScript also deeply supports imperative and object oriented programming, and has an optional class system with inheritance, calls to super, and more.

Coco 0 votes

Unfancy CoffeeScript

Coco is a CoffeeScript dialect that aims to be more radical and practical.


On its way to hide JavaScript's bad parts, CoffeeScript has accumulated own quirks: horrible variable scope, awkward ranges, confusing and/or pointless keywords, verbose file extension, and so on. Coco tries to amend them, entwining good parts of both.


  1. Respect JavaScript/ECMAScript semantics.
  2. Die for DRY.
  3. Perl over Ruby.
  4. Fewer keywords, punctuations and runtime errors.

IcedCoffeeScript 0 votes

Unfancy JavaScript w/ "Iced" Extensions

IcedCoffeeScript is a superset of CoffeeScript. The iced interpreter is a drop-in replacement for the standard coffee interpreter; it will interpret almost all existing CoffeeScript programs.

IcedCoffeeScript (ICS) adds two new keywords: await and defer. These additions simply and powerfully streamline asynchronous control flow, both on the server and on the browser. Say goodbye to callback pyramids; say adios to massive code rewrites when synchronization requirements change slightly. Say hello to clean, readable, maintainable control flow for network and asynchronous operations!

The golden rule of CoffeeScript was: “It's just JavaScript”. ICS is doing something deeper. It's selectively running code through a continuation-passing style conversion. Original-style CoffeeScript will compile as before, but code using the new ICS features will be less recognizable. Still, the compiled output is readable and pretty-printed, passes through JavaScript Lint without warnings.

Elm 0 votes

The Elm Programming Language

The Elm programming language aims to make web development more pleasant. Elm is a type-safe, functional reactive language that compiles to HTML, CSS, and JavaScript.

Elm's major distinguishing features are support for reactive programming and its focus on graphical user interfaces. Elm is also call-by-value and strongly / statically typed with type inference, so those of you already familiar with languages like Haskell or ML should be quite comfortable.

The language features mentioned above help catch errors in your code at compile time, but there are some errors that are external to your code, such as browser incompatabilities. By using HTML, CSS, and JavaScript as an assembly language, Elm can avoid some of these problems.

JS11 0 votes

A compact version of JavaScript

JS11 takes incomplete code and transforms it back into JavaScript. It's smart enough to add in various bits of redundant syntax, and can also transform some common errors and handy shortcuts into working JavaScript code. JS11 is a hybrid dialect that strives for greater readability and programmer effectiveness, whilst maintaining line-number parity with JavaScript. It consists of a language specification and a compiler module.

JS11 adds some nice-to-have features that people often use in JavaScript but have to write out the long way. This includes things like default argument values, named parameters in function calls, a nice way to create private variable scopes, and easy numbered loops.

JS11 can insert “function” keywords, semi-colons, empty function parameter lists, parentheses around for/if/while conditions, and missing wrappers on object literals. It can also insert var, &&, ||, ===, etc. wherever you've used the allowed alternatives.

JS11 uses a series of transformations to turn your code into runnable JavaScript. The compiler preserves line breaks, so the end product should debug line-for-line with your original source code. JS11-compiled JavaScript can be minified by Google Closure Compiler, or others, or deployed as-is.

JS11-generated code will work anywhere that JavaScript can, including browsers and server environments like Node, Akshell or RingoJS. The finished output debugs LINE-FOR-LINE, so if an error pops up on Line 750 you'll know exactly where to look - first time. It works with all the frameworks, libraries, and minifiers that you're already using, so there's no disruption.

JavaScript++ 0 votes

New, Powerful Language for Better Web Development.

JavaScript++ provides the same familiar C-style language syntax of JavaScript and brings modern language features such as classes;
block scoping and constants; pluggable type systems and type safety; packages and modules; comprehensive standard libraries; enhanced
regular expressions and PCRE; and more to JavaScript with almost no learning curve through an extended ES3 grammar.

As JavaScript grows and extends its reach beyond the web browser, and larger applications with increasing complexity begin to pop up, the original JavaScript syntax - which was designed for adding small programs and interactivity to web pages - needs to be extended to facilitate development of increasingly complex web applications. With features such as classes, static typing, and a package/module system, JavaScript++ enables large-scale software development that is maintainable, reliable, and economical.

JavaScript++ compiles to ES3-compatible JavaScript and is compatible with IE 5.5 and all versions of Firefox, Chrome, and the vast majority of web browsers dating back to 1999 for the client-side and Node.js, v8, SpiderMonkey, and Rhino on the server-side. Furthermore, JavaScript++ is backwards-compatible with all existing JavaScript code and libraries (jQuery, YUI et al), and JavaScript++ code can seamlessly and easily be embedded into your existing JavaScript code.

The JavaScript++ compiler supports regular JavaScript so there is practically no learning curve. Just pick and choose which JavaScript++ features you want to incorporate and learn on demand.

JavaScript++ incorporates features from Python, Perl, Java/C#, ES4, Harmony, Haskell, and more while incorporating its own unique features. The driving philosophy behind JavaScript++ is productivity, and it will make everything from small scripts to large applications easier and faster to write. Take the mundane out of your JavaScript code with JavaScript++!

JSX 0 votes

a faster, safer, easier alternative to JavaScript

JSX is a statically-typed, object-oriented programming language designed to run on modern web browsers.

JSX performs optimization while compiling the source code to JavaScript. The generated code runs faster than an equivalent code written directly in JavaScript. The gain may vary, but even the optimized JavaScript libraries like Box2D becomes faster when ported to JSX (we are observing 4% to 27% increase in performance).

In contrast to JavaScript, JSX is statically-typed and mostly type-safe. The quality of applications becomes higher when being developed using JSX, since many errors will be caught during the compilation process. It also offers debugging features at the compiler level as well.

JSX offers a solid class system much like the Java programming language, freeing the developers from working with the too-primitive prototype-based inheritance system provided by JavaScript. Expressions and Statements are mostly equal to JavaScript, so it is easy to for JavaScript programmers to start using JSX.
