## What it is
S.js is a small JavaScript reactive programming library combining an automatic dependency graph with a synchronous execution engine. It provides data signals and computations that automatically update when their dependencies change, with batched updates and automatic disposal.

## Use cases
- build reactive web apps with automatic updates
- manage state that changes over time in JavaScript
- create fine-grained reactive dependency graphs
- batch multiple state updates into a single transaction
- avoid manual subscription cleanup in reactive apps
- learn how signal-based reactivity works

## When to avoid
- you need a full-featured framework with components, routing, and ecosystem
- you want async or concurrent rendering semantics
- you need a library with active ongoing development and large community support

## Facets
- artifact type: library
- maturity: maintenance
- function: state-management, frontend-framework
- domain: web-development, frontend
- platform: browser
- tags: reactive-programming, signals, fine-grained-reactivity, dependency-tracking, nodejs, javascript
