Blazor WebAssembly uses the new WebAssembly browser feature to execute the .NET runtime in the browser. This way, it enables all developers to use the whole .NET code base and ecosystem in the implementation of applications capable of running in any WebAssembly-compliant browser. WebAssembly was conceived as a high-performance alternative to JavaScript. It is an assembly capable of running in a browser and obeying the same limitations as JavaScript code. This means that WebAssembly code, like JavaScript code, runs in an isolated execution environment that has very limited access to all machine resources.

WebAssembly differs from similar options of the past, like Flash and Silverlight, since it is an official W3C standard. More specifically, it became an official standard on December 5, 2019, so it is expected to have a long life. As a matter of fact, all mainstream browsers already support it.
