			[[File:WebAssembly_Logo.svg\|thumb\|right\|The official WebAssembly logo]]

	WebAssembly~~, often~~ abbreviated as Wasm, is a binary instruction format ~~that serves~~ as a compilation target for programming languages~~. It allows developers to run high-performance applications~~ on the web~~, bridging the gap between web~~ and ~~native~~ applications~~. In this article, we will explore the key features and benefits of WebAssembly, as well as its impact on web development~~.		'''WebAssembly''' (abbreviated '''Wasm''') is a binary instruction format for a stack-based virtual machine. It is designed as a portable compilation target for programming languages, enabling deployment on the web for client and server applications.

	== Overview ==		==Overview==
	WebAssembly is ~~designed to be~~ a low-level ~~virtual machine that runs code at near-native speed. It provides a compact binary~~ format that can be ~~efficiently transmitted over the network and quickly decoded by~~ web browsers. ~~This makes it an ideal choice~~ for ~~performance~~-~~critical applications~~, ~~such as games~~, ~~video editing tools~~, ~~and scientific simulations~~.		WebAssembly is a low-level bytecode format that can be executed in web browsers. It is designed to be a compilation target for high-level languages like [[C (programming language)\|C]], [[C++]], and [[Rust (programming language)\|Rust]], allowing these languages to run on the web with near-native performance.

	~~== History ==~~		WebAssembly is supported by all major web browsers, including [[Google Chrome]], [[Mozilla Firefox]], [[Microsoft Edge]], and [[Apple Safari]]. It is developed by the [[World Wide Web Consortium\|W3C]] and is considered a web standard.
	WebAssembly ~~was first announced in 2015 as a collaboration between~~ major ~~browser vendors~~, including Google, Mozilla, Microsoft, and Apple. ~~The goal was to create a portable and efficient binary format that could be executed on~~ the ~~web. Since then, WebAssembly has gained significant traction~~ and is ~~now supported by all major~~ web ~~browsers~~.

	== ~~Key~~ Features ==		==Features==
	WebAssembly ~~offers~~ several key features ~~that make it a powerful tool for web development~~:		WebAssembly provides several key features:

	[[Performance]]: WebAssembly is designed to execute ~~code~~ at near-native speed, ~~making it significantly faster than traditional~~ JavaScript~~. This allows~~ developers to ~~build complex applications that run smoothly~~ and ~~efficiently on the web~~.		* '''Portability''': WebAssembly code can run on any platform that has a WebAssembly runtime, making it highly portable.
			* '''Performance''': WebAssembly is designed to execute at near-native speed by taking advantage of common hardware capabilities.
			* '''Security''': WebAssembly runs in a sandboxed execution environment, which helps to protect the host system from potentially malicious code.
			* '''Interoperability''': WebAssembly can interoperate with JavaScript, allowing developers to call WebAssembly functions from JavaScript and vice versa.

	~~[[Portability]]:~~ WebAssembly is ~~platform-independent, meaning it can run~~ on ~~any device or operating system~~ that ~~supports~~ it~~. This makes it easier~~ for ~~developers to create applications that work seamlessly across different platforms~~.		==Architecture==
			WebAssembly is based on a stack machine architecture. It uses a binary format that is compact and efficient to parse, making it suitable for fast download and execution in web browsers.

	~~[[Security]]:~~ WebAssembly ~~runs~~ in ~~a sandboxed environment~~, ~~which provides an additional layer of security~~. ~~It ensures that~~ the code ~~executed within the browser cannot access sensitive user data or interfere with other web pages~~.		The WebAssembly module is the basic unit of code in WebAssembly. A module contains functions, tables, memories, and global variables. Functions are the primary building blocks of WebAssembly code, and they are defined using a simple instruction set.

	[[~~Interoperability~~]]~~: WebAssembly can be seamlessly integrated with existing web technologies~~, ~~such as JavaScript~~ and ~~HTML. This allows developers to leverage their existing codebase and libraries while taking advantage of the performance benefits offered by WebAssembly~~.		==Development==
			WebAssembly was first announced in 2015 and has since become a key technology for web development. It is developed by a consortium of major technology companies, including [[Google]], [[Mozilla]], [[Microsoft]], and [[Apple]].

	~~== Benefits ==~~		The WebAssembly specification is maintained by the [[World Wide Web Consortium\|W3C]] WebAssembly Working Group. The group is responsible for defining the core features of WebAssembly and ensuring its compatibility across different platforms.
	The ~~adoption~~ of WebAssembly ~~brings several benefits to web development:~~

	~~[[Improved Performance]]:~~ WebAssembly ~~allows developers to build high-performance~~ applications ~~that can handle computationally intensive tasks. This opens up new possibilities for web-based gaming~~, ~~multimedia editing, and other resource-intensive applications.~~		==Applications==
			WebAssembly is used in a variety of applications, including:

	~~[[Code Reusability]]~~: ~~With~~ WebAssembly, developers ~~can reuse existing code written~~ in ~~languages like C~~, ~~C++~~, and ~~Rust~~. ~~This eliminates~~ the ~~need~~ to ~~rewrite~~ code in ~~JavaScript, saving time~~ and ~~effort~~.		* '''Web applications''': WebAssembly allows developers to run complex applications in the browser, such as games, video editors, and CAD software.
			* '''Server-side applications''': WebAssembly can be used on the server side, enabling developers to run WebAssembly code in environments like [[Node.js]].
			* '''Embedded systems''': WebAssembly's portability makes it suitable for use in embedded systems and [[Internet of Things\|IoT]] devices.

	~~[[Broader Language Support]]:~~ WebAssembly ~~supports multiple programming languages~~, ~~enabling developers to choose the language that best suits their needs. This flexibility encourages innovation and allows developers to leverage their existing skills.~~		==Future Developments==
			The WebAssembly community is actively working on several future developments, including:

	~~[[Enhanced User Experience]]~~: ~~By leveraging~~ the ~~power~~ of WebAssembly~~, developers can create web~~ applications ~~that provide a seamless and responsive user experience~~. ~~This leads~~ to ~~higher user engagement and satisfaction~~.		* '''Garbage collection''': Adding support for garbage collection to improve the performance of languages that rely on it.
			* '''Threads''': Enhancing support for multithreading to allow WebAssembly applications to take advantage of multi-core processors.
			* '''SIMD''': Adding support for Single Instruction, Multiple Data (SIMD) to improve performance for certain types of computations.

	== ~~Conclusion~~ ==		==Related pages==
	WebAssembly is revolutionizing web development by providing a performant and portable execution environment for web applications. Its ability to run code at near-native speed, combined with its interoperability and security features, makes it an attractive choice for developers looking to build high-performance web applications. As WebAssembly continues to evolve and gain wider adoption, we can expect to see even more exciting developments in the web development landscape.		* [[JavaScript]]
