WebAssembly (WASM)

Knowledge Base / Glossary: "WebAssembly (WASM) is a low-level, portable, binary format that is designed to be executed in a web browser. It provides a way to run high-performance applications on the web, independent of the underlying platform or programming language."

WebAssembly (WASM) is a low-level, portable, binary format that is designed to be executed in a web browser. It provides a way to run high-performance applications on the web, independent of the underlying platform or programming language.

WebAssembly was developed as a joint effort by Mozilla, Google, Microsoft, and Apple, with the goal of creating a standard for executing code on the web that is fast, safe, and efficient. Unlike JavaScript, which is a high-level interpreted language, WebAssembly is a low-level language that is compiled to machine code. This means that WebAssembly can execute instructions much faster than JavaScript, making it ideal for running complex applications and high-performance games on the web.

One of the key benefits of WebAssembly is that it allows developers to compile existing code written in languages like C++, C#, or Rust into a format that can be run on the web. This means that developers can reuse their existing codebase, libraries, and frameworks without having to rewrite them for the web. This not only saves time and effort, but also ensures that the code is highly optimized and efficient.

In addition to running existing code on the web, WebAssembly also enables developers to write new code in languages like C++, Rust, and AssemblyScript, which can be compiled and run in the browser. This opens up a wide range of possibilities for building high-performance applications and games on the web that were previously not possible with JavaScript alone.

Overall, WebAssembly is a powerful tool for building rich and interactive web applications that can take advantage of the full capabilities of modern browsers and hardware. It is already being used in a wide range of applications, from web-based games and virtual reality experiences, to high-performance data visualization and scientific simulations. As the technology continues to evolve and gain adoption, it is likely to become an increasingly important part of the web development ecosystem.
