High-performance 2D spatial index for rectangles
RBush is a high-performance JavaScript library for 2D spatial indexing of points and rectangles by Vladimir Agafonkin, based on an optimized R-tree data structure with bulk insertion support.
Spatial index is a special data structure for points and rectangles that allows you to perform queries like "all items within this bounding box" very efficiently (e.g. hundreds of times faster than looping over all items). It's most commonly used in maps and data visualizations.
Node.js is an event-based server-side JavaScript engine.
