JavaScript helper functions for manipulating and analyzing GeoJSON data, including spatial calculations and geometric operations.
GeoJSON Utilities for JavaScript is a library of helper functions for manipulating and analyzing GeoJSON data in JavaScript applications. It provides spatial operations like line intersection detection, point-in-polygon testing, and distance calculations using the Haversine formula. The library solves the problem of performing common geographic data manipulations without relying on heavy GIS frameworks.
JavaScript developers working with geographic data in web mapping applications, spatial databases, or data visualization tools. It's particularly useful for those needing lightweight spatial calculations in browser or Node.js environments.
Developers choose this library because it offers a focused set of GeoJSON utilities with no external dependencies, making it easy to integrate. Its pure JavaScript implementation and MIT license provide flexibility for both open-source and commercial projects.

The library is designed as a pure JavaScript utility with no external dependencies, making it easy to integrate without bloating projects, as emphasized in its focus on lightweight spatial calculations.
It provides core operations like point-in-polygon testing and Haversine distance calculation, with clear examples in the README for tasks such as filtering by radius or detecting line intersections.
Can be loaded directly in browsers or via npm with simple require statements, as shown in the usage examples, lowering the barrier to entry for developers.
The MIT license allows unrestricted use in both open-source and commercial projects, providing legal flexibility without licensing concerns.
It only covers basic GeoJSON operations and lacks advanced capabilities like spatial indexing, buffer generation, or support for complex geometries such as MultiPolygon, which are common in modern GIS applications.
The project shows minimal recent updates and may not be actively maintained, risking compatibility issues with newer JavaScript environments and missing bug fixes or performance improvements.
Beyond basic examples, the README lacks comprehensive API documentation, error handling guides, or tutorials, forcing developers to rely on source code inspection for advanced use.
