Hey Reader, Today, I show you how combining Blazor and JavaScript can give you the best of both worlds. Let’s dive into how you can easily mix the power of these two technologies in your projects! Watch on YouTube 📺Check out the full tutorial on YouTube to see everything in action 👇 A Simple Example: Console Logging in BlazorImagine you’re working on a Blazor Server application, and you want to log the current count (of the Counter page) to the console.

When you click the button, you’ll see your custom log message in the console. Logging Complex ObjectsWant to log an entire object instead of just a text or value? You can easily do this with JavaScript too. For example, let’s say you have a

In your JavaScript, call this method:
When this JavaScript function runs, it calls the Blazor method and increments the counter. Wrapping UpCombining Blazor with JavaScript opens up a world of possibilities for your web development projects. Whether you’re logging data, handling complex objects, or calling Blazor methods from JavaScript, these techniques can make your applications more powerful and flexible.
