Geometric.js is a JavaScript library for doing geometry with points, lines, polygons, and angles. It uses plain arrays for geometry primitives, ships TypeScript declarations, and works in browsers and Node.js.

Use cases

• check if a point is inside a polygon
• compute line intersections in javascript
• rotate or scale a polygon
• calculate convex hull of points
• measure polygon perimeter and area
• compute distances and angles between points and lines
• perform polygon boolean operations

When to choose

• you need lightweight 2D geometry math in JavaScript without custom classes
• you want serializable plain-array geometry primitives for SVG or Canvas drawing
• you need TypeScript-friendly geometry helpers in Node or the browser

When to avoid

• you need 3D geometry or a full computational geometry engine
• you need a physics or game-engine-grade geometry system
• you need GPU-accelerated geometry processing
