pnpm, or Performant Node Package Manager, is one of the main JavaScript package managers, [2] developed in 2016 by Zoltan Kochan for the Node.js JavaScript runtime environment. [3] It focuses on being a disk space-efficient alternative to npm. [4] [5]
The Document Object Model (DOM) is a cross-platform and language-independent interface that treats an HTML or XML document as a tree structure wherein each node is an object representing a part of the document. The DOM represents a document with a logical tree. Each branch of the tree ends in a node, and each node contains objects. DOM methods allow programmatic access to the tree; with them one can change the structure, style or content of a document. Nodes can have event handlers attached to them. Once an event is triggered, the event handlers get executed.
JavaScript, often abbreviated as JS, is a programming language and core technology of the Web, alongside HTML and CSS. 99% of websites use JavaScript on the client side for webpage behavior.
ECMAScript is a standard for scripting languages, including JavaScript, JScript, and ActionScript. It is best known as a JavaScript standard intended to ensure the interoperability of web pages across different web browsers. It is standardized by Ecma International in the document ECMA-262.
A JavaScript engine is a software component that executes JavaScript code. The first JavaScript engines were mere interpreters, but all relevant modern engines use just-in-time compilation for improved performance.
A foreign function interface (FFI) is a mechanism by which a program written in one programming language can call routines or make use of services written or compiled in another one. An FFI is often used in contexts where calls are made into a binary dynamic-link library.
Dojo Toolkit is an open-source modular JavaScript library designed to ease the rapid development of cross-platform, JavaScript/Ajax-based applications and web sites. It was started by Alex Russell, Dylan Schiemann, David Schontzler, and others in 2004 and is dual-licensed under the modified BSD license or the Academic Free License.
TypeScript is a free and open-source high-level programming language developed by Microsoft that adds static typing with optional type annotations to JavaScript. It is designed for the development of large applications and transpiles to JavaScript. Because TypeScript is a superset of JavaScript, all JavaScript programs are syntactically valid TypeScript, but they can fail to type-check for safety reasons.
A JavaScript library is a library of pre-written JavaScript code that allows for easier development of JavaScript-based applications, especially for AJAX and other web-centric technologies. They can be included in a website by embedding it directly in the HTML via a script tag.
Node.js is a cross-platform, open-source JavaScript runtime environment that can run on Windows, Linux, Unix, macOS, and more. Node.js runs on the V8 JavaScript engine, and executes JavaScript code outside a web browser.
CommonJS is a project to standardize the module ecosystem for JavaScript outside of web browsers.
npm is a package manager for the JavaScript programming language maintained by npm, Inc., a subsidiary of GitHub. npm is the default package manager for the JavaScript runtime environment Node.js and is included as a recommended feature in the Node.js installer.
Socket.IO is an event-driven library for real-time web applications. It enables real-time, bi-directional communication between web clients and servers. It consists of two components: a client, and a server. Both components have a nearly identical API.
Electron is a free and open-source software framework developed and maintained by OpenJS Foundation. The framework is designed to create desktop applications using web technologies that are rendered using a version of the Chromium browser engine and a back end using the Node.js runtime environment. It also uses various APIs to enable functionality such as native integration with Node.js services and an inter-process communication module.
PM2 is a process manager for the JavaScript runtime Node.js.
Yarn is one of the main JavaScript package managers, developed in 2016 by Sebastian McKenzie of Meta for the Node.js JavaScript runtime environment. An alternative to the npm package manager, Yarn was created as a collaboration of Facebook, Exponent, Google, and Tilde to solve consistency, security, and performance problems with large codebases.
Deno is a runtime for JavaScript, TypeScript, and WebAssembly that is based on the V8 JavaScript engine and the Rust programming language. Deno was co-created by Ryan Dahl, who also created Node.js.
peacenotwar is a piece of malware, which has been characterized as protestware, created by Brandon Nozaki Miller. In March 2022, it was added as a dependency in an update for node-ipc, a common JavaScript dependency.
Bun is a JavaScript runtime, package manager, test runner and bundler built from scratch using the Zig programming language. It was designed by Jarred Sumner as a drop-in replacement for Node.js. Bun uses WebKit's JavaScriptCore as the JavaScript engine, unlike Node.js and Deno, which both use V8.
On March 22, 2016, software engineer Azer Koçulu took down the left-pad package that he had published to npm. Koçulu deleted the package after a dispute with Kik Messenger, in which the company forcibly took control of the package name kik. As a result, thousands of software projects that used left-pad as a dependency, including the Babel transcompiler and the React web framework, were unable to be built or installed. This caused widespread disruption, as technology corporations small and large, including Meta Platforms, PayPal, Netflix and Spotify, used left-pad in their software products.
