The only difference between an async generator and a conventional generator is that an async generator's next() method returns a Promise. The "for await..." of the statement is used to iterate over an async generator.
In this example, you use the throw keyword to an error using an error object. It will include a user-supplied error message, and then we will use a catch statement to correct the error.
In this example, we will pair the async generator with the yield keyword. Using a catch statement, we will first declare a promise that is denied and which has the error statement in the reject() method.
In this example, the async generator function displays the use of the yield and await keywords.
The example shows the iterator value using the operator and function. The iterator shows data from start to end values of the async generator function.
