    TypeScript

    TypeScript

    Application-scale JavaScript

    TypeScript is an open source programming language that is a typed superset of JavaScript. It adds optional static typing to JavaScript, which can support tools for large-scale JavaScript applications for any browser, host and OS. TypeScript compiles to clean, simple JavaScript, and uses existing JavaScript code and libraries. It also offers support for the latest and evolving JavaScript features, such as async functions and decorators.

    V Programming Language

    V Programming Language

    Simple, fast, safe, compiled language for developing software

    Simple language for building maintainable programs. You can learn the entire language by going through the documentation over a weekend, and in most cases, there's only one way to do something. This results in simple, readable, and maintainable code. Despite being simple, V gives a lot of power to the developer and can be used in pretty much every field, including systems programming, webdev, gamedev, GUI, mobile, science, embedded, tooling, etc. V avoids doing unnecessary allocations in the first place by using value types, and string buffers, promoting a simple abstraction-free code style. Most objects (~90-100%) are freed by V's auto-free engine: the compiler inserts necessary free calls automatically during compilation. A remaining small percentage of objects is freed via GC. The developer doesn't need to change anything in their code. "It just works", like in Python, Go, or Java, except there's no heavy GC tracing everything or expensive RC for each object.

    Svelte

    Svelte

    Cybernetically enhanced web apps

    Svelte is a new way to build web applications. It's a compiler that takes your declarative components and converts them into efficient JavaScript that surgically updates the DOM. Svelte shifts as much work as possible out of the browser and into your build step. No more manual optimizations, just faster, more efficient apps. Write breathtakingly concise components using languages you already know, HTML, CSS, and JavaScript. Oh, and your application bundles will be tiny as well. Built-in scoped styling, state management, motion primitives, form bindings and more — don't waste time trawling npm for the bare essentials. It's all here.

    Marked

    Marked

    A markdown parser and compiler. Built for speed

    A low-level markdown compiler for parsing markdown without caching or blocking for long periods of time. Light-weight while implementing all markdown features from the supported flavors & specifications. Available as a command-line interface (CLI) and running in client- or server-side JavaScript projects. The only completely secure system is the one that doesn't exist in the first place. Having said that, we take the security of Marked very seriously. To prevent ReDoS attacks you can run marked on a worker and terminate it when parsing takes longer than usual. Marked can be run in a worker thread on a node server, or a web worker in a browser. Only current and LTS Node.js versions are supported. End-of-life Node.js versions may become incompatible with Marked at any point in time.

    webpack

    webpack

    A bundler for Javascript and friends

    webpack is a module bundler that is primarily used for bundling JavaScript files for usage in a browser, though it can also transform, bundle, or package just about any resource or asset, including images and styles. webpack packs many modules into a few bundled assets. It can bundle ES Modules, CommonJS, and AMD modules, and create a single bundle or multiple chunks through code-splitting that are asynchronously loaded at runtime. It supports all browsers that are ES5-compliant, has a rich plugin interface that makes it very flexible, and enables the use of loaders to preprocess files.

    Mint

    Mint

    A refreshing programming language for the front-end web

    Mint has all the tools you need to write error-free, easily readable, and maintainable applications in record time. In Mint you can style elements directly with CSS using style blocks. Inside a style block, you can nest as many sub selectors and media queries as you like. Interpolate any Mint expressions in any value using the interpolation syntax. You can even use if and case expressions inside any block to apply styles conditionally. In Mint a store contains and manages some data. Stores are globally accessible and can be connected to components. When the data in a store changes the connected components are re-rendered. In Mint routing is a language feature instead of a library. Routes can be defined in a routes block, with support for typed path parameters. The runtime handles clicks on anchor tags and navigates in a smart way so you don't have to. You can inline any JavaScript code easily by using bacticks.

    Rollup

    Rollup

    A module bundler for JavaScript

    Rollup is a module bundler for JavaScript which compiles small pieces of code into something larger and more complex, such as a library or application. It uses the new standardized format for code modules included in the ES6 revision of JavaScript, instead of previous idiosyncratic solutions such as CommonJS and AMD. ES modules let you freely and seamlessly combine the most useful individual functions from your favorite libraries. This will eventually be possible natively everywhere, but Rollup lets you do it today. Rollup can be used either through a command line interface with an optional configuration file, or else through its JavaScript API. Rollup allows you to write your code using the new module system, and will then compile it back down to existing supported formats such as CommonJS modules, AMD modules, and IIFE-style scripts. This means that you get to write future-proof code.

    Hogan.js

    Hogan.js

    A compiler for the Mustache templating language

    Hogan.js is a 2.5k JS templating engine developed at Twitter. Use it as a part of your asset packager to compile templates ahead of time or include it in your browser to handle dynamic templates. If you're developing with Node.js, just use NPM to add the Hogan package. Hogan.js was developed against the mustache test suite, so everything that holds true for templates is also the case for hogan.js. That means you get variables, sections, lambdas, partials, filters, and everything else you've come to expect from mustache templating, only much, much faster. Use hogan.compile() to precompile your templates into vanilla JS. It's best to serve your templates precompiled whenever you can (rather than the raw templates), as parsing is the most time consuming operation. Once compiled, call the render() method with a context and optional partials object. If supplying partials, you can compile them ahead of time, or pass string templates.

    C-Lesh and SMW Engine

    C-Lesh is a game programming language for 2D games.

    C-Lesh is a game programming language for 2D games - mainly arcade and platform games. When combined with the Super Mario World (SMW) engine you can create awesome 2D platform games like Super Mario World. This language evolved from a "clone" of TI-BASIC which I began developing when I was having memory (segmentation fault) bugs with C. C-Lesh lacks memory allocation and destruction. There is no need to use pointers and you can never get memory leaks or program crashes caused by memory leaks. As C-Lesh is somewhat primitive you may like it if you are into C. I'd say its a step up from C for 2D games. Everything is set - all you need is a sprite sheet and some programming knowledge.
