API
visit(tree[, test], visitor[, reverse])
This function works exactly the same as unist-util-visit-parents
, but visitor
has a different signature.
next? = visitor(node, index, parent)
Instead of being passed an array of ancestors, visitor
is invoked with the node
’s index
and its parent
. The optional return value next
is documented in unist-util-visit-parents
’s README.
Otherwise the same as unist-util-visit-parents
.
