Class BaseJavaScriptInterop

Helper class that simplifies calling JavaScript functions in a WebView document. Helps with formatting calls using ExecuteScriptAsync() and properly formatting/encoding parameters.

Recommend that you subclass this object for your application and then implement wrapper methods around each interop call you make into the JavaScript document

Operations are applied to the BaseInvocationTarget which is the base object that operations are run on. This can be the window. or any globally accessibly object ie. window.textEditor..

You can use Invoke, Set, Get to access object properties, or you can use ExecuteScriptAsync to fire raw requests.

Parameterize helps with encoding parameters when calling methods and turning them into string parseable values using JSON.
