/* @abstract Calls the given JavaScript string as a function, passing the given named arguments to that function.
 @param javaScriptString The JavaScript string to call as a function.
 @param arguments A dictionary representing the arguments to be passed to the function call.
 @param contentWorld The WKContentWorld in which to call the JavaScript function.
 @param completionHandler A block to invoke with the return value of the function call, or with the asynchronous resolution of the function's return value.
 @discussion The JavaScript string is treated as an anonymous JavaScript function that can be called with named arguments.
 Do not format your string as one of the variants of function call available in JavaScript.
 Instead pass in a JavaScript string representing the function text, formatted for evaluation.
 For example do not pass in the string:
     function(x, y, z) { return x ? y : z; }
 Instead pass in the string:
     return x ? y : z;

 The arguments dictionary supplies the values for those arguments which are serialized into JavaScript equivalents.
 For example:
     @{ @"x" : @YES, @"y" : @1, @"z" : @2 };

 Combining the above arguments dictionary with the above JavaScript string, a function with the arguments "x", "y", and "z" is called with values YES, 1, and 2 respectively.

 Allowed argument types are:
 NSNumber, NSString, NSDate, NSArray, NSDictionary, and NSNull.
 Any NSArray or NSDictionary containers can only contain objects of those types.

 No matter which WKContentWorld you use to call your JavaScript function, you can make changes to the underlying web content. (e.g. the Document and its DOM structure)
 Such changes will be visible to script executing in all WKContentWorlds.
 Calling your JavaScript function can leave behind other changes to global state visibile to JavaScript. (e.g. `window.myVariable = 1;`)
 Those changes will only be visibile to scripts executed in the same WKContentWorld.

 Your completion handler will be called with the return value of your JavaScript function.
 If your JavaScript does not explicitly return any value, that undefined result manifests as nil being passed to your completion handler.
 If your JavaScript returns null, that result manifests as NSNull being passed to your completion handler.

 JavaScript has the concept of a "thenable" object, which is any JavaScript object that has a callable "then" property.
 The most well known example of a "thenable" object is a JavaScript promise.
 If your JavaScript returns a "thenable" object WebKit will call "then" on the resulting object and wait for it to be resolved.

 If the object calls "fulfill", your completion handler will be called with the result.
 If the object calls "reject", your completion handler will be called with a WKErrorJavaScriptAsyncFunctionResultRejected error containing the reject reason in the userInfo dictionary.
 If the object is garbage collected before it is resolved, your completion handler will be called with an error indicating that it will never be resolved.

 Since the function is a JavaScript "async" function you can use JavaScript "await" on those objects inside your function text.
 For example:
     var p = new Promise(function (r) {
         r(42);
     });
     await p;
     return p;

 The above function text will create a promise that will fulfull with the value 42, wait for it to resolve, then return the fulfillment value of 42.
*/

/* @abstract Evaluates the given JavaScript string.
 @param javaScriptString The JavaScript string to evaluate.
 @param contentWorld The WKContentWorld in which to evaluate the JavaScript string.

 @discussion The completionHandler is passed the result of the script evaluation or an error.
 No matter which WKContentWorld you use to evaluate your JavaScript string, you can make changes to the underlying web content. (e.g. the Document and its DOM structure)
 Such changes will be visible to script executing in all WKContentWorlds.
 Evaluating your JavaScript string can leave behind other changes to global state visibile to JavaScript. (e.g. `window.myVariable = 1;`)
 Those changes will only be visibile to scripts executed in the same WKContentWorld.
 evaluateJavaScript: is the best way to set up global state for future JavaScript execution in a given world. (e.g. Importing libraries/utilities that future JavaScript execution will rely on)
 Once your global state is set up, consider using callAsyncJavaScriptFunction: for more flexible interaction with the JavaScript programming model.
