Function: generateAsync()

Returns an infinite async iterable that yields seed for its first value and then yields the awaited result of applying fn to its previously yielded value for every subsequent value.

Example​

console.log(
  await pipe(
    generateAsync(previousValue => previousValue + previousValue, `sloth`),
    takeAsync(3),
    reduceAsync(toArray()),
  ),
)
//=> [ 'sloth', 'slothsloth', 'slothslothslothsloth' ]

generateAsync(fn)​

generateAsync<Value>(fn): (seed) => AsyncIterable<Value, any, any>
