Variable nthChild`Const`

nthChild: {
    flip: (n: number) => <A>(self: Tree<A>) => Option<Tree<A>>;
    <A>(n: number, self: Tree<A>): Option<Tree<A>>;
    <A>(self: Tree<A>): (n: number) => Option<Tree<A>>;
} = ...

Return the Nth child tree of a tree or Option.none() if index is out-of-bounds or if given tree is a leaf.

Negative indexes are handled as offsets from the end of the forest with -1 being the last child, -2 the child before it, and so on.
