Function itr8FromImpureFunction

itr8FromImpureFunction<T>(f: (() => T | Promise<T>)): IterableIterator<T> | AsyncIterableIterator<T>
Turns a parameterless function into an Iterator that will produce results using the input function's return value. In case the function returns a promise, the result will be an AsyncIterator. Useful for 'impure' stuff like Math.random, or Date.now etc.

Example
```
pipe(
 itr8FromImpureFunction(Math.random),
 take(3),
 itr8ToArray
); // => [0.2511072995514807, 0.04918679946517224, 0.48479881173432826]
```
Returns
an iterator
