Creating Blazor Components the right way

not to sound rude but, this video doesn't make any sense

Thanks Mr.Dan for your video.
I hope you talk about Refresh JWT Token in API and how Blazor wasm app should detect if the token will expire and refresh it in the background.

How do you register an event like onClick event for this type of component?

Is it possible to do scoped css and scoped javarcript. So like how other javascript frameworks you can easy write css and javscruot that will only affect this component. Is that possible?

Is there a reason you use an Character[ ] vs IEnumerable<Character> ?

The razor.cs file reminds me of the code behind of WPF. Thanks.

My thanks for this as you start to enjoy develop blazor apps to see some more advanced concepts has opened my eyes on different methods to achieve the same goals

Well done. I enjoyed listening to your rationale about how & why. Looking forward to the next installments. Go Blazor!
