As Blazor WebAssembly is a .NET framework, it means it can share code between itself and an ASP.NET Core app through a shared class library. One code block can be written and shared across multiple .NET applications. This gives it an advantage over JavaScript frameworks, such as Angular and React, where a separate validation script would need to be coded using JavaScript. A good example of this is validating a file when it is being uploaded. The Blazor WebAssembly app can validate the file first and only upload it to the ASP.NET Core app if it passes the test.
