QuickJS
An ECMAScript engine is a program that executes source code written in a version of the ECMAScript language standard, for example, JavaScript. Just-in-time compilation engines These are new generation ECMAScript engines for web browsers, all implementing just-in-time compilation (JIT) or variations of that idea. The performance benefits for just-in-time compilation make it much more suitable for web applications written in JavaScript. * Carakan: A JavaScript engine developed by Opera Software ASA, included in the 10.50 release of the Opera web browser, until switching to V8 with Opera 15 (released in 2013). * Chakra (JScript9): A JScript engine used in Internet Explorer. It was first previewed at MIX 10 as part of the Internet Explorer 9 Platform Preview. * Chakra: A JavaScript engine previously used in older versions of Microsoft Edge, before being replaced by V8. * SpiderMonkey: A JavaScript engine in Mozilla Gecko applications, including Firefox. The engine currently in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ECMAScript 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 ...

Gecko (software)
Gecko is a browser engine developed by Mozilla. It is used in the Firefox browser, the Thunderbird email client, and many other projects. Gecko is designed to support open Internet standards, and is used by different applications to display web pages and, in some cases, an application's user interface itself (by rendering XUL). Gecko offers a rich programming API that makes it suitable for a wide variety of roles in Internet-enabled applications, such as web browsers, content presentation, and client/server. Gecko is written in C++ and JavaScript, and, since 2016, additionally in Rust. It is free and open-source software subject to the terms of the Mozilla Public License version 2. Mozilla officially supports its use on Android, Linux, macOS, and Windows. History Development of the layout engine now known as Gecko began at Netscape in 1997, following the company's purchase of DigitalStyle. The existing Netscape rendering engine, originally written for Netscape Navigator 1.0 and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ActionScript
ActionScript is an object-oriented programming language originally developed by Macromedia Inc. (later acquired by Adobe). It is influenced by HyperTalk, the scripting language for HyperCard. It is now an implementation of ECMAScript (meaning it is a superset of the syntax and semantics of the language more widely known as JavaScript), though it originally arose as a sibling, both being influenced by HyperTalk. ActionScript code is usually converted to byte-code format by the compiler. ActionScript is used primarily for the development of websites and software targeting the Adobe Flash platform, originally finding use on Web pages in the form of embedded SWF files. ActionScript 3 is also used with Adobe AIR system for the development of desktop and mobile applications. The language itself is open-source in that its specification is offered free of charge and both an open source compiler (as part of Apache Flex) and open source virtual machine (Tamarin) are available.

Tamarin (software)
Tamarin is a discontinued free software virtual machine with just-in-time compilation (JIT) support intended to implement the 4th edition of the ECMAScript (ES4) language standard. Tamarin source code originates from ActionScript Virtual Machine 2 (AVM2) developed by Adobe Systems, as introduced within Adobe Flash Player 9, which implements ActionScript 3 scripting language. ActionScript Virtual Machine 2 was donated as open-source to Mozilla Foundation on November 7, 2006, to develop Tamarin as a high-performance virtual machine, with the support from broad Mozilla community, to be used by Mozilla and Adobe Systems in the next generation of their JavaScript and ActionScript engines with the ultimate aim to unify the scripting languages across web browsers and Adobe Flash platform and ease the development of better performing rich web applications. Tamarin and Mozilla The source code, including the just-in-time compiler and conservative garbage collector, was donated to the Mozill ...

CoreCLR
The domain name net is a generic top-level domain (gTLD) used in the Domain Name System of the Internet. The name is derived from the word ''network'', indicating it was originally intended for organizations involved in networking technologies, such as Internet service providers and other infrastructure companies. However, there are no official restrictions and the domain is now a general-purpose namespace. It is still popular with network operators and the advertising sector, and it is often treated as an alternative to . History is one of the original top-level domains (the other six being , , , , , and ) despite not being mentioned in RFC 920, having been created in January 1985. Verisign, the operator of after acquiring Network Solutions, held an operations contract that expired on 30 June 2005. ICANN, the organization responsible for domain management, sought proposals from organizations to operate the domain upon expiration of the contract. Verisign regained the cont ...

Common Language Runtime
The Common Language Runtime (CLR), the virtual machine component of Microsoft .NET Framework, manages the execution of .NET programs. Just-in-time compilation converts the managed code (compiled intermediate language code) into machine instructions which are then executed on the CPU of the computer. The CLR provides additional services including memory management, type safety, exception handling, garbage collection, security and thread management. All programs written for the .NET Framework, regardless of programming language, are executed in the CLR. All versions of the .NET Framework include CLR. The CLR team was started June 13, 1998. CLR implements the Virtual Execution System (VES) as defined in the Common Language Infrastructure (CLI) standard, initially developed by Microsoft itself. A public standard defines the Common Language Infrastructure specification. With Microsoft's move to .NET Core, the CLI VES implementation is known as CoreCLR instead of CLR. See also * ...

NET Framework
The .NET Framework (pronounced as "''dot net"'') is a proprietary software framework developed by Microsoft that runs primarily on Microsoft Windows. It was the predominant implementation of the Common Language Infrastructure (CLI) until being superseded by the cross-platform .NET project. It includes a large class library called Framework Class Library (FCL) and provides language interoperability (each language can use code written in other languages) across several programming languages. Programs written for .NET Framework execute in a software environment (in contrast to a computer hardware, hardware environment) named the Common Language Runtime (CLR). The CLR is an process virtual machine, application virtual machine that provides services such as security, memory management, and exception handling. As such, computer code written using .NET Framework is called "managed code". FCL and CLR together constitute the .NET Framework. FCL provides the user interface, data access, d ...

JScript
JScript is Microsoft's legacy dialect of the ECMAScript standard that is used in Microsoft's Internet Explorer 11 and older. JScript is implemented as an Active Scripting engine. This means that it can be "plugged in" to OLE Automation applications that support Active Scripting, such as Internet Explorer, Active Server Pages, and Windows Script Host. It also means such applications can use multiple Active Scripting languages, e.g., JScript, VBScript or PerlScript. JScript was first supported in the Internet Explorer 3.0 browser released in August 1996. Its most recent version is JScript 9.0, included in Internet Explorer 9. JScript 10.0 is a separate dialect, also known as JScript .NET, which adds several new features from the abandoned fourth edition of the ECMAScript standard. It must be compiled for .NET Framework version 2 or version 4, but static type annotations are optional. JScript has been criticized for being insecure and having multiple security bugs "exploited by n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Safari (web Browser)
Safari is a web browser developed by Apple Inc., Apple. It is built into macOS, iOS, and iPadOS, and uses Apple's open-source software, open-source browser engine, WebKit, which was derived from KHTML. Safari was introduced in Mac OS X Panther in January 2003. It was included with the iPhone since the latter's first generation, which came out in 2007. At that time, Safari was the fastest browser on the Mac. Between 2007 and 2012, Apple maintained a Microsoft Windows, Windows version, but abandoned it due to low market share. In 2010, Safari 5 introduced a reader mode, extensions, and developer tools. Safari 11, released in 2017, added Intelligent Tracking Prevention, which uses artificial intelligence to block web tracking. Safari 13 added support Apple Pay, and authentication with FIDO2 Project, FIDO2 security keys. Its interface was redesigned in Safari 15.

WebKit
WebKit is a browser engine developed by Apple and primarily used in its Safari web browser, as well as on the iOS and iPadOS version of any web browser. WebKit is also used by the BlackBerry Browser, PlayStation consoles beginning from the PS3, the Tizen mobile operating systems, a browser included with the Amazon Kindle e-book reader, and on Nintendo consoles beginning from the 3DS Internet Browser and onward. WebKit's C++ application programming interface (API) provides a set of classes to display Web content in windows, and implements browser features such as following links when clicked by the user, managing a back-forward list, and managing a history of pages recently visited. WebKit started as a fork of the KHTML and KJS libraries from KDE, and has since been further developed by KDE contributors, Apple, Google, Nokia, Bitstream, BlackBerry, Sony, Igalia, and others. WebKit supports macOS, Windows, Linux, and various other Unix-like operating systems. On April 3, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
