    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.

    Webpack Encore

    Webpack Encore

    A simple but powerful API for processing and compiling assets

    Symfony ships with a pure-JavaScript library, called Webpack Encore, that makes it a joy to work with CSS and JavaScript. You can use it, use something else, or create static CSS and JS files in your public/ directory directly and include them in your templates. Webpack Encore is a simpler way to integrate Webpack into your application. It wraps Webpack, giving you a clean & powerful API for bundling JavaScript modules, pre-processing CSS & JS, and compiling and minifying assets. Encore gives you a professional asset system that's a delight to use. Encore is inspired by Webpacker and Mix, but stays in the spirit of Webpack, using its features, concepts and naming conventions for a familiar feel. It aims to solve the most common Webpack use cases. Encore is made by Symfony and works beautifully in Symfony applications. But it can easily be used in any application in any language!

    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.
