Description-en: fully persistent balanced binary search tree - browser library
Functional-red-black-tree is a fully persistent red-black tree
written 100% in JavaScript.
.
Functional (or fully persistent) data structures
allow for non-destructive updates.
So if you insert an element into the tree,
it returns a new tree with the inserted element
rather than destructively updating the existing tree in place.
Doing this requires using extra memory,
and if one were naive it could cost as much as reallocating the entire tree.
Instead, this data structure saves some memory
by recycling references to previously allocated subtrees.
This requires using only O(log(n)) additional memory per update
instead of a full O(n) copy.
.
Some advantages of this is
that it is possible to apply insertions and removals to the tree
while still iterating over previous versions of the tree.
Functional and persistent data structures can also be useful
in many geometric algorithms
like point location within triangulations or ray queries,
and can be used to analyze the history of executing various algorithms.
This added power though comes at a cost,
since it is generally a bit slower to use a functional data structure
than an imperative version.
However, if your application needs this behavior
then you may consider using this module.
.
This package provides functional-red-black-tree
for use directly in web browsers.
