This repo contains several simple balanced binary search tree JavaScript implementations to experiment, benchmark and play with.
bbtree.js: Andersson tree (based on Arne Andersson's Balanced Search Trees Made Simple paper and Julienne Walker's tutorial)bsarray.js: pseudo-BBST internally stored as a simple JS arrayllrb.js: Sedgewick's Left-Leaning Red-Black Tree
Benchmarks contain comparisons with functional-red-black-tree and js_bintrees.
The goal is to create the fastest and at the same time the simplest JS balanced binary search tree library.
Example usage of trees:
// create a tree using a custom compare function
var tree = bbtree(function (a, b) { return a - b; });
// insert items
tree.insert(1, 'foo');
tree.insert(5, {bar: 2});
// find an item
var node = tree.find(3);
console.log(node.key, node.value);
// TODO remove & other methods
