+{{alias}}( iterator )
+ Returns an iterator which cumulatively tests whether every iterated value is
+ falsy.
+
+ The returned iterator immediately returns `false` upon encountering a truthy
+ value, for all subsequent iterations.
+
+ If provided an iterator which does not return any iterated values, the
+ returned iterator returns `true`.
+
+ Parameters
+ ----------
+ iterator: Object
+ Input iterator over which to iterate.
+
+ Returns
+ -------
+ iterator: Object
+ Iterator.
+
+ Iterator Protocol
+ -----------------
+ The returned iterator protocol-compliant object has the following properties:
+
+ next: Function
+ Returns an iterator protocol-compliant object containing the next
+ iterated value (if one exists) assigned to a `value` property and a
+ `done` property having a boolean value indicating whether the iterator
+ is finished.
+
+ return: Function
+ Finishes an iterator and returns a single (optional) argument in an
+ iterator protocol-compliant object.
+
+ Examples
+ --------
+ > var arr = {{alias:@stdlib/array/to-iterator}}( [ 0, 0, 0, 0, 1 ] );
+ > var it = {{alias}}( arr )
+ > var v = it.next().value
+ true
+ > v = it.next().value
+ true
+ > v = it.next().value
+ true
+ > v = it.next().value
+ true
+ > v = it.next().value
+ false
+ > var bool = it.next().done
+ true
