Execute Javascript

Execute Javascript code. Javascript string evaluation occurs in the context of an anonymous function with one optional string argument Arg. Function executes asynchronously if Wait for Return Value? is FALSE (default) or synchronously if TRUE. When executing synchronously, use the 'return' statement to output a value as Return Value, or 'throw' to output an Exception string. By default, the returned value must be a primitive Javascript type (number, string, bool, or null), which is converted to a string to provide Return Value. If Return Non-primitive Types? is TRUE, the return value can be any Javascript type, and is processed by 'JSON.stringify' to return a string; objects and arrays are encoded as JSON, and string values include surrounding quotes and escaped characters.
