PureScript is a statically typed, purely functional programming language that compiles to JavaScript. It is designed as a cross-platform frontend language for building safe web applications, utilizing a static type system and a JavaScript compiler to ensure program correctness across browser and server environments. The language is distinguished by its emphasis on mathematical purity, featuring a robust type system with first-class support for monads. It provides a sophisticated toolset for static verification, including algebraic data types, type classes, and automatic type inference to reje

recursion-context is a set of PHP utilities for traversing and modifying deep data hierarchies. It provides a recursive variable processor designed to apply transformations across nested arrays and objects while maintaining stability. The project distinguishes itself through a recursion depth controller and reference tracking to prevent infinite loops and memory exhaustion when processing circular data structures. It monitors the level of nesting during traversal to avoid stack overflows. These tools cover hierarchical data transformation and nested data processing, allowing for stateful vis

collect.js is a dependency-free JavaScript library that provides a fluent, chainable interface for manipulating arrays and objects. It mirrors the Laravel Collection API, offering a consistent set of methods for data transformation across JavaScript and Laravel backend environments. The library stores collection data as plain arrays internally and supports fluent method chaining, where each method returns a new collection instance. The library distinguishes itself by closely replicating the Laravel Collection API in JavaScript, mapping each PHP method to an equivalent JavaScript implementatio

gcoord is a coordinate conversion library that transforms geographic coordinates between China's three major map coordinate systems: WGS-84, GCJ-02, and BD-09. It handles the offset corrections required by national encryption policies, converting GPS or API-derived coordinates to align with the projections used by Chinese map providers like Baidu, Gaode, and Google China. The library provides direct conversions between all three systems, including WGS-84 to GCJ-02, WGS-84 to BD-09, GCJ-02 to BD-09, and their reverse transformations. It processes individual coordinate pairs, batches of coordin

This project is a reactive state management library designed for handling complex form data and validation logic. It utilizes observable-based patterns to synchronize user interface components with underlying data models, ensuring that form states remain consistent throughout an application. The library provides a structured approach to managing form initialization, field tracking, and lifecycle events. The library distinguishes itself through its support for deeply nested data structures and hierarchical composition, allowing for recursive validation and dynamic updates within complex object
