Export assignment sparsearray2iteratorRight

• sparsearray2iteratorRight(src: ArrayLike<any>, mapFcn?: MapFunction, thisArg?: any): Iterator

• Returns an iterator which iterates from right to left over each element in a sparse array-like object.

  Notes

  • For dynamic array resizing, the only behavior made intentionally consistent with iterating from left to right is when elements are pushed onto the beginning (end) of an array. In other words, iterating from left to right combined with [].push() is consistent with iterating from right to left combined with [].unshift().

  Parameters

  • src: ArrayLike<any>

    input value

  • Optional mapFcn: MapFunction

    function to invoke for each iterated value

  • Optional thisArg: any

    execution context

  Returns Iterator

  iterator

  Example

  var iter = sparsearray2iteratorRight( [ 1, , 3, 4 ] );
  
  var v = iter.next().value;
  // returns 4
  
  v = iter.next().value;
  // returns 3
  
  v = iter.next().value;
  // returns 1
