Blazor is a single-page web app framework built on .NET that operates in the browser using WebAssembly, allowing C# to be used for web development by leveraging JavaScript interoperability for accessing the browser's DOM API. Since WebAssembly cannot directly interact with the DOM, Blazor uses JavaScript interop to call JavaScript functions from .NET and vice versa, facilitating the use of existing JavaScript libraries within Blazor applications. This interop capability is crucial for overcoming the limitations of WebAssembly and for providing flexibility and backward compatibility in web development. As Blazor is still an experimental framework, it allows developers to fall back on JavaScript when needed, providing a migration path for users familiar with JavaScript-based libraries. The framework supports creating abstractions around browser features, providing C# methods to enhance functionality at the application level. As the ecosystem of interop libraries grows, developers are likely to spend more time in C# and less in JavaScript, which could simplify the development process and improve efficiency. Blazor's integration with monitoring solutions like LogRocket allows developers to better manage frontend complexities by providing enhanced visibility into application performance and user interactions.
