Variable: atConcur()

const atConcur: {<Index>(index): <Value>(concurIterable) => ConcurOptional<Value>; <Index, Value>(index, concurIterable): ConcurOptional<Value>; }

Defined in: splices.d.ts:977

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.
