Function: generate()

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

Example​

import { generate, pipe, reduce, take, toArray } from 'lfi'

console.log(
  pipe(
    `sloth`,
    generate(previousValue => `${previousValue} ${previousValue}`),
    take(4),
    reduce(toArray()),
  ),
)
//=> [
//=>   'sloth',
//=>   'sloth sloth',
//=>   'sloth sloth sloth sloth',
//=>   'sloth sloth sloth sloth sloth sloth sloth sloth'
//=> ]
