Function isAsyncGenerator

isAsyncGenerator(value: any): value is AsyncGeneratorFunction
Checks if the provided value is an AsyncGeneratorFunction
Parameters
- value: any
  Value to be checked
Returns value is AsyncGeneratorFunction
True if the value is an AsyncGeneratorFunction, false otherwise
Since
0.12.3

Remarks
This function checks if the provided value is an AsyncGeneratorFunction, which is a special type of function that returns an AsyncGenerator and can be used with the await keyword. Note that this function does not check if the function is a generator or an async function. And when using TypeScript and targetting earlier versions of JavaScript, the type of the function may NOT be AsyncGeneratorFunction and instead be a regular function.
Example
```
async function* asyncGenFn() { }
isAsyncGenerator(asyncGenFn);           // true
isAsyncGenerator(function() {});        // false
isAsyncGenerator(async function() {});  // false
isAsyncGenerator(function* () {});      // false
isAsyncGenerator(null);                 // false
isAsyncGenerator(undefined);            // false
```
