Function: atConcur()

Returns a concur iterable containing the value at the given index of concurIterable in iteration order, or an empty concur iterable if index is out of bounds.

WARNING: This function linearly iterates up to index because concur iterables do not support random access.

Throws​

if index is not a non-negative integer.

Example​

const concurIterable = asConcur([`sloth`, `more sloth`, `even more sloth`])

console.log(
  await pipe(
    concurIterable,
    atConcur(1),
    getConcur,
  ),
)
//=> 'more sloth'

atConcur(index)​

atConcur<Index>(index): <Value>(concurIterable) => ConcurOptional<Value>
