Bun is a JavaScript runtime, package manager, test runner and bundler built from scratch using the Zig programming language. [3] [4] It was designed by Jarred Sumner as a drop-in replacement for Node.js. Bun uses WebKit's JavaScriptCore as the JavaScript engine, [5] unlike Node.js and Deno, which both use V8.

Contents

It supports bundling, minifying, server-side rendering (Svelte, Nuxt.js, Vite). Bundling refers to the process of combining multiple files and assets like JavaScript, CSS, and HTML into a single file, or a smaller number of files, to reduce the number of server requests and enhance performance. [6] Minifying is a technique of compressing these files by removing unnecessary characters (like whitespace, comments, etc.) without affecting their functionality, further optimizing website loading times. Bun provides an API to decide whether to preserver some readability by e.g. keeping whitespace. [6]

The runtime supports foreign function interface (FFI), SQLite3, TLS 1.3, and DNS resolution. It also comes bundled in with common tools like file editing, HTTP servers, Websocket, and hashing. [7]

Since Bun 1.1 the runtime supports Windows 10 and later (along with Linux and MacOS). [8] [9] It also introduced a cross-platform Bun Shell for running some Bash commands without extra dependencies. [8] [9]

NativeScript is an open-source framework to develop mobile apps on the iOS and Android platforms. It was originally conceived and developed by Progress. At the end of 2019 responsibility for the NativeScript project was taken over by long-time Progress partner, nStudio. In December 2020 nStudio also oversaw the induction of NativeScript into OpenJS Foundation as an Incubating Project. NativeScript apps are built using JavaScript, or by using any programming language that transpiles to JavaScript, such as TypeScript. NativeScript supports the Angular and Vue JavaScript frameworks. Mobile applications built with NativeScript result in fully native apps, which use the same APIs as if they were developed in Xcode or Android Studio. Additionally, software developers can re-purpose third-party libraries from CocoaPods, Maven, and npm.js in their mobile applications without the need for wrappers.

Enonic XP uses an application framework for coding server logic with JavaScript, and has no need for SQL as it ships with an integrated content repository. The CMS is fully decoupled, meaning developers can create traditional websites and landing pages, or use XP in headless mode, that is without the presentation layer, for loading editorial content onto any device or client. Enonic is used by major organizations in Norway, including the national postal service Norway Post, the insurance company Gjensidige, the national lottery Norsk Tipping, the Norwegian Labour and Welfare Administration, and all the top football clubs in the national football league for men, Eliteserien.
