Geometric Calculations - Calculates distances, angles, and spatial overlaps between points and rectangles.
Coordinate Distance Calculators - Calculates distances and intersections between points and bounding rectangles in a 2D coordinate system.
Data Validation Predicates - Provides a toolkit of predicates for verifying numeric properties, date ranges, and string patterns.
Numeric Property Validators - Implements predicates to verify numeric properties such as parity, primality, and signs.
Scalar Mathematical Utilities - Provides basic numeric computations including factorials, Fibonacci numbers, and averages.

Reason is a strongly typed functional language and multi-target compiler designed to produce either JavaScript for web environments or native machine code for operating systems. It serves as an OCaml-compatible language that shares an abstract syntax tree with OCaml, providing a practical syntax for the OCaml ecosystem. The project functions as a type-safe frontend language, incorporating JSX support to build user interfaces through structural elements that translate into type-safe function calls. It enables deep integration with the JavaScript ecosystem, allowing the use of existing librarie
