Function: uniqueByConcur()

Returns a concur iterable containing the values of concurIterable, except values for which fn returns a value awaitable to the same value are deduplicated.

When values are deduplicated, the value earlier in iteration order wins.

Example​

console.log(
  await pipe(
    asConcur([`sloth`, `sleep`, `fast`, `slow`, `mean`]),
    uniqueByConcur(word => word.length),
    reduceConcur(toArray()),
  ),
)
//=> [ 'sloth', 'fast' ]

uniqueByConcur(fn)​

uniqueByConcur<Value>(fn): (concurIterable) => ConcurIterable<Value>

Returns a concur iterable containing the values of concurIterable, except values for which fn returns a value awaitable to the same value are deduplicated.

When values are deduplicated, the value earlier in iteration order wins.
