AsyncGeneratorFunction

The AsyncGeneratorFunction object provides methods for async generator functions. In JavaScript, every async generator function is actually an AsyncGeneratorFunction object.

Note that AsyncGeneratorFunction is not a global object. It can be obtained with the following code:

js
const AsyncGeneratorFunction = async function* () {}.constructor;

AsyncGeneratorFunction is a subclass of Function.

Try it

Constructor

AsyncGeneratorFunction()

Creates a new AsyncGeneratorFunction object.

Instance properties

Also inherits instance properties from its parent Function.

These properties are defined on AsyncGeneratorFunction.prototype and shared by all AsyncGeneratorFunction instances.

AsyncGeneratorFunction.prototype.constructor

The constructor function that created the instance object. For AsyncGeneratorFunction instances, the initial value is the AsyncGeneratorFunction constructor.

AsyncGeneratorFunction.prototype.prototype

All async generator functions share the same prototype property, which is AsyncGenerator.prototype. Each async generator function instance also has its own prototype property. When the async generator function is called, the returned async generator object inherits from the async generator function's prototype property, which in turn inherits from AsyncGeneratorFunction.prototype.prototype.

AsyncGeneratorFunction.prototype[@@toStringTag]

The initial value of the @@toStringTag property is the string "AsyncGeneratorFunction". This property is used in Object.prototype.toString().

Instance methods

Inherits instance methods from its parent Function.
