2JS

2js is a name used by several software projects in the JavaScript ecosystem. It does not denote a single standardized project, but is instead used by different tools and libraries that serve distinct purposes. The most common references are to a lightweight 2D graphics library and to a transpiler or compiler-related project.

The 2js graphics library is a small JavaScript toolkit designed to facilitate drawing and animating 2D graphics in web browsers. It typically provides a compact API for rendering shapes, images, and text on an HTML5 canvas, along with basic animation support via requestAnimationFrame and simple event handling. The library emphasizes a minimal footprint and straightforward integration with existing web projects.

The 2js compiler or transpiler project is described as a tool that translates code written in a domain-specific language or a compact JavaScript-like dialect into standard JavaScript. It often supports modular compilation, source maps, and compatibility with common build tools, targeting developers who want a specialized syntax or preprocessing step in their JavaScript workflow.

Other 2js projects may include utilities, polyfills, education resources, or experimental language features. Because there is no centralized specification, specifics such as API, licensing, and maintenance vary by project. Readers should consult the individual repository documentation for current features and compatibility notes.
