Description

This RFC proposes adding the package @stdlib/iter/cuany, which cumulatively tests whether at least one iterated value is truthy. The function should be a transform iterator, continuing to iterate while source iterator values are available.

var array2iterator = require( '@stdlib/array/to-iterator' );

var arr = array2iterator( [ false, false, false, true, false ] );

var it = iterCuAny( arr );

var v = it.next().value;
// returns false

v = it.next().value;
// returns false

v = it.next().value;
// returns false

v = it.next().value;
// returns true

v = it.next().value;
// returns true

var bool = it.next().done;
// returns true
