WebAssembly and the Future of the Web

History

In 2015, engineers at Mozilla were looking for ways to improve the performance of web applications. WebAssembly emerged as an open standard in response. The technology offers memory efficiency and faster execution speeds compared to JavaScript - though JavaScript is sufficient for most use cases given modern browser capabilities. WASM primarily serves as a good complement for edge cases. All major browsers - Chrome, Firefox, Edge, and Safari - now support the standard for production use.

New Possibilities

WebAssembly enables the compilation of existing code for execution in the browser, allowing languages other than JavaScript. A key practical benefit lies in expanded accessibility for developers. Developers familiar with established or modern languages can now build web applications. Microsoft’s Blazor framework demonstrates this - it allows the use of the .NET framework in web contexts, which is particularly valuable in enterprise environments.

The technology supports simultaneous development for web and desktop through shared codebases - logic changes only need to be made once, not platform-specifically. Companies with legacy systems benefit significantly through easier web porting. While existing software can’t simply be run in the browser, essential parts - particularly logic and data processing - remain reusable, saving time and costs. Developers can stay in familiar working environments without having to learn new technologies. AutoCAD is an example of this approach, having successfully migrated desktop applications to web browsers.

Future

WebAssembly will accelerate the trend of migrating applications to the internet. For cloud infrastructure, the technology promises smaller, space-saving programs with improved startup and execution performance.

Conclusion

Originally developed for performance improvements, WebAssembly now creates innovative use cases for web applications and makes the web platform increasingly accessible and economical for businesses.
