What Is WebAssembly (Wasm), and What Can It Do for You?
Table of Contents
What is WebAssembly?
A low-level language called WebAssembly is created to be executed on a virtual machine and produces code that is highly efficient. It is similar to assembly language in this respect. However, unlike assembly language, WebAssembly is not specific to a particular platform or architecture. This makes it possible to compile code written in a variety of languages to WebAssembly, including C, C++, and Rust.
How Does WebAssembly Work?
WebAssembly (Wasm) code is compiled to a binary format that is then loaded into a virtual machine. The virtual machine is a runtime environment that executes the WebAssembly code. Developers designed the virtual machine to be fast and efficient, with a small footprint that can easily embed in web browsers.

Examples of WebAssembly Applications
There are a growing number of applications that use WebAssembly, ranging from games and simulations to productivity tools and compilers.
Games and Simulations
For example, the popular game engine Unity has added support for WebAssembly, making it possible to build games that run in the browser with performance close to that of native code.

Developers can use WebAssembly to create browser-based productivity solutions, such as the Figma design tool, which utilizes WebAssembly to perform computationally expensive activities, including rendering graphics.
By compiling the Rust programming language to WebAssembly, developers can run Rust code in the browser with performance comparable to that of native code, since WebAssembly can act as a target for compilers, enabling code written in multiple languages to run in the browser.
WebAssembly (Wasm) is a powerful new technology that presents several advantages for web developers, as it allows low-level languages to run in the browser with performance comparable to that of native code.
