Node.js
Node.js is an open-source server environment. Node.js is cross-platform and runs on Windows, Linux, Unix, and macOS. Node.js is a back-end JavaScript runtime environment. Node.js runs on the V8 JavaScript Engine and executes JavaScript code outside a web browser. Node.js lets developers use JavaScript to write command line tools and for server-side scripting. The functionality of running scripts server-side produces dynamic web page content before the page is sent to the user's web browser. Consequently, Node.js represents a "JavaScript everywhere" paradigm, unifying web-application development around a single programming language, rather than different languages for server-side and client-side scripts. Node.js has an event-driven architecture capable of asynchronous I/O. These design choices aim to optimize throughput and scalability in web applications with many input/output operations, as well as for real-time Web applications (e.g., real-time communication programs and br ...

OpenJS Foundation
The OpenJS Foundation is an organization that was founded in 2019 from a merger of JS Foundation and Node.js Foundation. OpenJS Promotes the JavaScript and web ecosystem by hosting projects and funds activities that benefit the ecosystem. The OpenJS Foundation is made up of 38 open source JavaScript projects including Appium, Dojo, jQuery, Node.js, Node-RED and webpack. Founding members included Google, Microsoft, IBM, PayPal, GoDaddy, and Joyent. History jQuery Foundation jQuery Foundation was founded in 2012 as 501(c)(6) non-profit organization to support the development of the jQuery and jQuery UI projects. jQuery is the most widely adopted JavaScript library according to web analysis as of 2012. Prior to the jQuery Foundation, the jQuery project was a member of the Software Freedom Conservancy since 2009. The jQuery Foundation also advocates on behalf of web developers to improve web standards through its memberships in the W3C, and Ecma TC39 (JavaScript). It created a s ...

Ryan Dahl
Ryan Dahl (born 1981) is an American software engineer who is best known for creating the Node.js JavaScript runtime as well as the Deno JavaScript/TypeScript runtime. Biography Dahl grew up in San Diego, California. His mother bought him an Apple IIc when he was six years old, one of his first experiences with technology. Dahl attended a community college in San Diego and later transferred into UC San Diego where he studied mathematics. He went on to attend grad school for Mathematics at the University of Rochester where he studied algebraic topology, which he found "very abstract and beautiful" for a couple of years but later got bored of it because "it was not so applicable to real life". Ruby work After graduating, Dahl entered a Ph.D. program, but eventually dropped out, since he did not want to devote the rest of his life to mathematics. Instead, he left for South America, where he started developing web applications in Ruby. Node.js On May 27, 2009, Dahl released his ...

JavaScript
JavaScript (), often abbreviated as JS, is a programming language that is one of the core technologies of the World Wide Web, alongside HTML and CSS. As of 2022, 98% of Website, websites use JavaScript on the Client (computing), client side for Web page, webpage behavior, often incorporating third-party Library (computing), libraries. All major Web browser, web browsers have a dedicated JavaScript engine to execute the Source code, code on User (computing), users' devices. JavaScript is a High-level programming language, high-level, often Just-in-time compilation, just-in-time compiled language that conforms to the ECMAScript standard. It has dynamic typing, Prototype-based programming, prototype-based object-oriented programming, object-orientation, and first-class functions. It is Programming paradigm, multi-paradigm, supporting Event-driven programming, event-driven, functional programming, functional, and imperative programming, imperative programming paradigm, programmin ...

JavaScript Engine
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. JavaScript engines are typically developed by web browser vendors, and every major browser has one. In a browser, the JavaScript engine runs in concert with the rendering engine via the Document Object Model. The use of JavaScript engines is not limited to browsers. For example, the V8 engine is a core component of the Node.js and Deno runtime systems. Since ECMAScript is the standardized specification of JavaScript, ECMAScript engine is another name for these engines. With the advent of WebAssembly, some engines can also execute this code in the same sandbox as regular JavaScript code. History The first JavaScript engine was created by Brendan Eich in 1995 for the Netscape Navigator web browser. It was a rudimentary interpreter for the nascent language Eich inven ...

Server-side Scripting
Server-side scripting is a technique used in web development which involves employing scripts on a web server which produces a response customized for each user's (client's) request to the website. The alternative is for the web server itself to deliver a static web page. Scripts can be written in any of a number of server-side scripting languages that are available (see below). Server-side scripting is distinguished from client-side scripting where embedded scripts, such as JavaScript, are run client-side in a web browser, but both techniques are often used together. Server-side scripting is often used to provide a customized interface for the user. These scripts may assemble client characteristics for use in customizing the response based on those characteristics, the user's requirements, access rights, etc. Server-side scripting also enables the website owner to hide the source code that generates the interface, whereas, with client-side scripting, the user has access to all ...

V8 (JavaScript Engine)
V8 is a free and open-source JavaScript engine developed by the Chromium Project for Google Chrome and Chromium web browsers. The project’s creator is Lars Bak. The first version of the V8 engine was released at the same time as the first version of Chrome: 2 September 2008. It has also been used on the server side, for example in Couchbase and Node.js. History The V8 assembler is based on the Strongtalk assembler. On 7 December 2010, a new compiling infrastructure named Crankshaft was released, with speed improvements. In version 41 of Chrome in 2015, project TurboFan was added to provide more performance improvements with previously challenging workloads such as asm.js. Much of V8's development is strongly inspired by the Java HotSpot Virtual Machine developed by Sun Microsystems, with the newer execution pipelines being very similar to those of HotSpot's. In 2016, the Ignition interpreter was added to V8 with the design goal of reducing the memory usage on small memory A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Real-time Web
The real-time web is a computer network, network web using technologies and practices that enable users to receive information as soon as it is published by its authors, rather than requiring that they or their software check a source periodically for updates. Difference from real-time computing The real-time web is different from real-time computing in that there is no knowing when, or if, a response will be received. The information types transmitted this way are often short messages, status updates, news alerts, or links to longer documents. The content is often "soft" in that it is based on the social web—people's opinions, attitudes, thoughts, and interests—as opposed to hard news or facts. History Examples of real-time web are Facebook's newsfeed, and Twitter, implemented in social networking, search, and news sites. Benefits are said to include increased user engagement ("flow") and decreased server loads. In December 2009 real-time search facilities were added to Goog ...

Web Application
A web application (or web app) is application software that is accessed using a web browser. Web applications are delivered on the World Wide Web to users with an active network connection. History In earlier computing models like client-server, the processing load for the application was shared between code on the server and code installed on each client locally. In other words, an application had its own pre-compiled client program which served as its user interface and had to be separately installed on each user's personal computer. An upgrade to the server-side code of the application would typically also require an upgrade to the client-side code installed on each user workstation, adding to the technical support, support cost and decreasing productivity. In addition, both the client and server components of the application were usually tightly bound to a particular computer architecture and operating system and porting them to others was often prohibitively expensive for ...

Dynamic Web Page
A server-side dynamic web page is a web page whose construction is controlled by an application server processing server-side scripts. In server-side scripting, parameters determine how the assembly of every new web page proceeds, and including the setting up of more client-side processing. A client-side dynamic web page processes the web page using JavaScript running in the browser as it loads. JavaScript can interact with the page via Document Object Model, or DOM, to query page state and modify it. Even though a web page can be dynamic on the client-side, it can still be hosted on a static hosting service such as GitHub Pages or Amazon S3 as long as there isn't any server-side code included. A dynamic web page is then reloaded by the user or by a computer program to change some variable content. The updating information could come from the server, or from changes made to that page's DOM. This may or may not truncate the browsing history or create a saved version to go back ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Front End And Back End
In software engineering, the terms frontend and backend (or sometimes referred to as back end or back-end) refer to the separation of concerns between the presentation layer (''frontend''), and the data access layer (''backend'') of a piece of software, or the physical infrastructure or hardware. In the client–server model, the client is usually considered the frontend and the server is usually considered the backend, even when some presentation work is actually done on the server itself. Introduction In software architecture, there may be many layers between the hardware and end user. The ''front'' is an abstraction, simplifying the underlying component by providing a user-friendly interface, while the ''back'' usually handles data storage and business logic. In telecommunication, the ''front'' can be considered a device or service, while the ''back'' is the infrastructure that supports provision of service. A rule of thumb is that the client-side (or "frontend") is any comp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
