Instantiating Objects and Accessing Properties in Blazor

Blazor's .NET 10 introduces new JavaScript interop capabilities, specifically the `InvokeConstructorAsync` method, which allows C# code to instantiate JavaScript objects and hold typed references via `IJSObjectReference`. Previously, developers had to rely on `eval`, global `window` variables, and string-based invocations — approaches prone to code injection, memory leaks, and naming collisions. With the new API, each component gets its own JS object instance with a controlled lifecycle, cleaner parameter passing, and no memory leaks. Additionally, `GetValueAsync` and `SetValueAsync` methods enable reading and writing JS object properties directly from C#. The post demonstrates these improvements using a lightbox image gallery integrated with a Telerik Blazor Data Grid.
